Hi @spacedesk-marcel, @spacedesk-christian,
Thank you for your willingness to help me solve my problem.
I would exclude Windows Firewall and Antivirus, Spacedesk is added to the exceptions. I have the router from the network operator, and I cannot change any settings.
I checked the HTML5 Viewer connection, and unfortunately it doesn’t work. But as in the case of Spacedesk Driver Console, HTML5 connects via the cellular network (mobile data).
I don’t know what other changes may have occurred on my network, maybe the operator changed some settings.
Thank you and best regards
