Synology authentification rejected
I'm trying to connect from several and different computers to my Teamviewer Synology IOT client but each time i got same message "Authentification rejected".
I try from my desktop and Adnroid on the same network and at my office from another laptop and my Android : same issue.
I was able to add synology client into my account without any problem and appear as ready to connect.
Any idea or solution ?
Need to NAT some ports/IP ?
