Unable to login after change on static IP

We are changing ISP provider, I still have both old and new Internet active.
After restarting, I can't login! This is what the login page looks like. Please advise.

And your 3CX is located where? You're using a HTTP (80/5000) or HTTPS (443/5001) URL? After restarting what, the 3CX instance?

Hello @sohcy

Please make sure that all 3CΧ services are up and running. If a service is not running try to manually start it. Make sure you check the Nginx service as well
