Issue
When attempting to log in to your Segment account, you may encounter network connection errors in your web browser - such as net::ERR_INTERNET_DISCONNECTED, net::ERR_NAME_NOT_RESOLVED, or net::ERR_TIMED_OUT - which prevent successful authentication and block access to the Segment Console.

Environment
Segment Console
Cause
These browser errors typically indicate local network restrictions, domain name system (DNS) resolution failures, local firewall/security policy interference, or conflicts with active Virtual Private Network (VPN) and proxy configurations blocking traffic to Twilio or Segment authentication domains.
Resolution
- Open a new Incognito or Private browsing window to attempt logging in with browser extensions disabled by default.
- Temporarily disable any active VPN, proxy server, or local firewall configurations that may be filtering your web traffic.
- Manually turn off browser extensions - especially third-party password managers and ad-blockers, that may have permission to run in private windows and block network requests.
- Clear your web browser's cache and cookies, then reload the login page.
- Attempt to log in using an entirely different network (such as a mobile hotspot) to rule out local network, router, or Internet Service Provider (ISP) restrictions.
- If the issue persists, open your browser’s developer tools, navigate to the Network tab, refresh the login page, and look for failed requests targeting Segment or Twilio domains to identify any specific HTTP status codes.
Additional Information
If connection issues continue after completing these steps, please contact Segment Support and share a screenshot of the failed requests in your developer tools' Network tab or export a HAR log to help our team diagnose the root cause.
