If you use OpenID to log in to Gerrit, you need to make sure that the OpenID provider can reach your Gerrit server.
I recently tried setting up Gerrit when I was at my university, on a WPA Enterprise network behind a firewall, and God knows what other security and it just doesn't work, it still got the same error as you.
Later, at home, on the WPA2 core network, I tried OpenID login again and it worked fine.
In addition, you need port forwarding to make sure that the corresponding requests are redirected to the Gerrit server.
Remember that Gerrit and Google OpenId no longer work *. However, you can use Yahoo OpenID.
