If Claude Code opens normally but then shows “Unable to connect to Anthropic services”, the problem is usually somewhere in the connection between your computer and Anthropic. You may also see an error like “Failed to connect to console.anthropic.com: ECONNRESET”, which makes it look like Claude Code itself is broken even though that is not always the case.
This kind of error can come from your internet connection, a VPN, proxy settings, firewall, DNS problem, or even a temporary issue on Anthropic’s side. Sometimes everything else on your PC works fine, which makes the error a bit more confusing. This article is for you if Claude Code opens but fails to connect to Anthropic, shows ECONNRESET, or stops before login or authentication can finish.
What Does the “Unable to Connect to Anthropic Services” Error Mean?
The message basically means Claude Code tried to contact Anthropic but the connection did not complete properly. If you also see ECONNRESET, it normally means the connection was opened and then unexpectedly closed or reset before the request finished.
That does not automatically mean your internet is fully down. You may still be able to open websites and use other apps normally. The reset can happen because of a temporary Anthropic problem, unstable Wi-Fi, a VPN or proxy, firewall filtering, or something on the network path that is interrupting the connection.
So the error is more about connection failure than a bad Claude Code command.
What Causes Claude Code to Lose Connection to Anthropic?
There are a few common reasons this can happen. Some are simple, like unstable internet, while others are more specific to work or school networks.
Common causes include:
- Temporary Anthropic service issues
- Weak or unstable Wi-Fi
- Router connection resets
- VPN interference
- Incorrect proxy settings
- Windows Firewall blocking traffic
- Antivirus HTTPS scanning
- DNS problems
- Corporate SSL inspection
- Outdated Claude Code version
- Authentication session problems
- Proxy environment variables pointing to the wrong server
- Country or regional availability restrictions
The important thing is not to jump straight into reinstalling Claude Code. Start with the network side first because that is where this error usually points.
How to Fix Unable to Connect to Anthropic Services
If Claude Code is showing this connection error, follow the fixes below one by one. Start with the status and network checks before changing any proxy or certificate settings.
1. Check Anthropic’s Service Status
Before changing anything on your PC, check whether Anthropic is having a service problem.
If Claude Code was working normally and suddenly stopped, the issue may not be on your side. An outage or authentication problem can affect Claude Code even when your computer and internet are fine.
Check Anthropic’s official status page and look for any active issue involving Claude, authentication, the API, or related services. If there is an outage, the best option is usually to wait and try again later.
Do this first because there is no point changing firewall rules or reinstalling software if the service is temporarily having trouble.
2. Restart Your Internet Connection and Test Another Network
An unstable connection can cause ECONNRESET even when websites still seem to load normally. Claude Code may be making a connection that gets interrupted for a second, and that is enough to stop authentication.
Start simple. Restart your router, reconnect to Wi-Fi or Ethernet, close Claude Code, then reopen it.
If the problem stays, try another network for a quick test. A mobile hotspot works fine for this.
If Claude Code connects normally on the hotspot but fails on your usual internet connection, that tells you quite a lot. The issue is more likely related to your router, ISP, DNS, firewall, or network filtering rather than Claude Code itself.
You do not need to keep using the hotspot. It is just a useful test.
3. Disable VPN or Proxy Temporarily
If you are using a VPN, turn it off for a moment and try Claude Code again.
A VPN changes the route your connection takes to Anthropic. Sometimes that route can be unstable, blocked, or reset before the connection finishes. It can also make your connection appear to come from another country or region.
Proxy settings can cause the same sort of problem. Claude Code can work through HTTP and HTTPS proxies, but the settings need to be correct.
If you intentionally use proxy environment variables, check values such as:
- HTTP_PROXY HTTPS_PROXY
A wrong proxy address, dead proxy server, or old environment variable can stop Claude Code from reaching Anthropic at all.
If you are on a work or school network, do not try to bypass its security controls. In that case, it is better to check with the network administrator.
4. Check Windows Firewall and Antivirus
Windows Firewall or antivirus software can sometimes block or inspect secure connections.
This is more common when antivirus software has features called something like:
- HTTPS scanning
- SSL scanning
- Web protection
- Encrypted traffic scanning
For testing, you can temporarily disable that specific web or HTTPS scanning feature and then try Claude Code again.
Do not leave your antivirus turned off permanently. This is only to see whether security software is causing the reset.
For Windows Firewall, it is better to allow Claude Code or the required Anthropic traffic rather than disabling the whole firewall. If Claude suddenly works after changing a security setting, you have probably found where the problem is coming from.
5. Reset DNS and Windows Network Settings
If the connection still fails, Windows networking may need a refresh.
Open Command Prompt as Administrator and run these commands one by one:
ipconfig /flushdns
netsh winsock reset
netsh int ip reset
The first command clears the DNS cache. The second resets Winsock, which Windows uses for network communication. The third resets TCP/IP settings.
After running all three, restart your computer.
This can help if Claude Code is trying to use old DNS information or Windows networking has ended up in a bad state. It is a pretty common fix for strange connection problems where browsers work but one app does not.
6. Check Whether Claude Is Supported in Your Country
The Claude Code error screen may say the service isn’t available in your country. That does not mean this is always the cause, but it is worth checking.
Anthropic has a supported countries and regions list for Claude and API access. If your country is supported, then the problem is probably somewhere else, such as your VPN, network route, or firewall.
A supported country can still get the same error, especially if a VPN makes the connection appear to come from another region.
So do not assume the region warning automatically explains everything. Check the official list first.
7. Update Claude Code and Run claude doctor
If the network side looks fine, check your Claude Code installation.
You can try updating Claude Code with:
claude update
After that, run:
claude doctor
claude doctor can help identify setup or installation problems and is much more useful than immediately uninstalling everything.
This is also worth doing if Claude Code started failing after a system update or if you have been using the same installation for a long time.
On Windows, the shell and environment can matter too. If you are using a setup that depends on Git for Windows or WSL, make sure those parts are still working correctly.
8. Check Corporate Proxy and SSL Certificate Settings
This fix mainly applies to office, school, enterprise, or other managed networks.
Some organizations route internet traffic through a proxy and inspect secure HTTPS connections using their own SSL certificates. If Claude Code does not trust that certificate properly, the connection may fail or reset.
You may see environment variables such as:
HTTP_PROXY HTTPS_PROXY
For custom certificates, environments may also use settings like:
SSL_CERT_FILE NODE_EXTRA_CA_CERTS
Do not download random certificate files from the internet. If you are on a managed network, ask the network or IT administrator which proxy and CA certificate settings you should use.
This is one of those cases where the error may only happen on the work network but disappear at home or on a mobile hotspot.
How to Prevent the Error From Coming Back
You cannot prevent every connection problem, but a few small things can reduce how often this happens.
- Keep Claude Code updated
- Avoid leaving old proxy variables configured
- Use a stable internet connection
- Keep Windows networking and security updates current
- Check VPN settings if connection problems keep returning
- Make sure managed firewalls allow required Anthropic traffic
- Keep corporate CA certificates configured properly
- Check Anthropic’s status before changing local settings
If the error suddenly appears after months of normal use, check the simple things first. A network or service issue is often more likely than a completely broken installation.
FAQs
What Does ECONNRESET Mean in Claude Code?
ECONNRESET means the connection between Claude Code and the remote service was unexpectedly closed before it finished. The reset can happen on your computer, somewhere on the network, through a VPN or proxy, or on the remote side. It does not necessarily mean your whole internet connection is down.
Why Can’t Claude Code Connect to console.anthropic.com?
Claude Code needs to reach Anthropic services during login and authentication. If that connection is blocked or reset, you may see an error mentioning console.anthropic.com. VPN problems, proxy settings, DNS issues, firewall filtering, antivirus HTTPS scanning, or a temporary service problem can all cause it.
Can a VPN Cause “Unable to Connect to Anthropic Services”?
Yes, a VPN can sometimes cause this error. It may route your connection through a server that is unstable, blocked, or located in another region, and the connection can reset before Claude Code finishes. Turning the VPN off temporarily is a useful test, but it should not be used to bypass regional availability rules.
Do I Need to Reinstall Claude Code?
Usually not as the first step. Check Anthropic status, your network, VPN, proxy, firewall, and DNS first, then try claude update and claude doctor. Reinstalling makes more sense only after those checks fail and you have reason to think the local installation itself is damaged.
Is Claude Code Available in Every Country?
No, Claude Code availability depends on Anthropic’s supported countries and regions. The list can change, so it is better to check the current official availability rather than guessing from the error message alone. Even in a supported country, you can still get a connection error because of VPN, proxy, or network problems.
Final Thoughts
If Claude Code shows “Unable to connect to Anthropic services” with an ECONNRESET error, start with the simple checks. Look at Anthropic’s service status, restart your network, test another connection, and turn off any VPN or proxy temporarily. If that does not help, move on to firewall, DNS, Claude Code updates, and proxy or certificate settings.
The main thing is not to reinstall everything straight away. This error usually points to the connection path rather than the whole Claude Code installation. If Claude Code still shows ECONNRESET, share whether you are using normal Wi-Fi, a VPN, or a work or school network, because that usually tells us which fix to try next.
