I can't log in or synchronize data

If you cannot log in to Termius or synchronize your data, and you see a spinner or an error message, check the following:

  1. Make sure your firewall allows incoming and outgoing traffic for these domains: api.termius.com, grpc.termius.com, account.termius.com, termius.com, and termi.us. Also make sure these domains are reachable from your network.

  2. Check whether your network performs TLS interception. This can break the WebSocket connection. If needed, add an exception for Termius domains.

  3. Make sure the connection to grpc.termius.com uses HTTP/2. Termius requires it to work correctly.

If the issue persists, please submit a support requestarrow-up-right.
