Thank you for the additional information.
Unfortunately, I wasn't able to recreate your issue. Could you try to connect to your VPN once again and then extract for me two files (important note: extract those files only when you got a Timed out error, otherwise I won't be able to see the issue):
1. OVPN logs file. You can get it by right-clicking on OVPN, navigating to your new user > View Log
2. Routers troubleshoot file. To get the TS file from RMS you'll need to navigate to Management > Devices > Select your RUT device > Action > Extract troubleshoot
Send me those two files and I will check what is causing your issues.
