Browser issues often involve cache, extensions, system proxy settings or multiple proxy apps. Change one thing at a time to identify the cause.

Steps

Check whether other apps can connect. If messaging apps also fail, start with connection troubleshooting.

Close other proxy tools, VPN apps and browser proxy extensions. Keep only NiceCat VPN running.
Open the same site in a private window. If that works, disable extensions one by one or clear your browser cache.
Switch to another available location and reconnect. Some third-party websites restrict regions or require an additional login.
If the issue continues, record your browser name, version, affected URL and error message, then contact support.
