Self signed certificates not allowed in Teams tabs linked website
When using tab with linked website via https
If website uses self-signed certificate (e.g. internal sites) then this results in error in Teams: This site won't load in our desktop app
In browser is OK since you can tell system to trust the root CA used for self-signing. But Teams ignores this.

That's a real problem if Teams do not allow self signed ssl certs (a.k.a. as locally hosted intranet application where you won't get an official cert easily).
It can't be that MS tell us to move everything to their cloud and remote services integrate them as tab in MS Teams.
I understand that this would provoke some failure messages if I'm not connected to the intranet but this is acceptable for internal usage.
