Unable to connect to server on Windows (app / all browsers / even on my Mac now)

Unable to connect to server on Windows (app / all browsers / even on my Mac now)

Hi everyone,

My Zoho Mail App on Windows, which has worked fine until now, has been unable to connect upload anything. In fact it returns the message: Unable to connect to server

I can't access my emails, not on the Windows App nor in any browser I've tried (Opera, Brave, Edge, nothing works). And now, my Mac is experiencing the same problem.

However, I can access from my iPhone (iOS app, same network, same location).

Any ideas?
