how to fix cannot connect mattermost to windows 10

Hello, i have tried that troubleshooting guide and tried on two different Laptop but the issue is persistent and the behaviour is the same across devices, connections, app (both Mattermost and mattermost classic).

I have installed three different machines on three different VM, without solving the issue.

I think it’s an app issue.

Hi @luuhachi, what error message are you seeing?

Hey there @luuhachi in addition to letting us know about the error message as Amy Blais mentioned, do also provide us with screenshots of what happens when you try to login to Mattermost as well. It’d help us understand the issue better :slight_smile:
