Hello,
Could we try uninstalling Windows App version 11.0.7 (2452) and then install an earlier version from the App Center to see if the issue is related to the new version?
However, error 0x104 typically points towards a network problem. It would be advisable to check with your VPN provider to ensure all necessary settings for RDP are correctly configured. A common challenge when using RDP over a VPN is the split tunneling configuration, which might need adjustment on the VPN's settings page.
I hope this information helps.
Best regards,
Karlie Weng
