Cannot use OTP Manager App with VPN connection

[niclasheinz]

Thanks for the great app @matteo-convertino. I always have a vpn running on my Samsung Galaxy S23. When connected to it, the app cannot synchronize new entries. When I end the vpn, the entries are synchronized. Can you implement the ability to run a vpn and use the app?

Best regards, Niclas

It seems strange that the problem directly depends on the VPN. Maybe it could be a stupid question, but I have to ask you: when you are connected to the VPN, if you try to access your Nextcloud via browser, is it reachable?
If it is reachable, app logs may be useful.

The Nextcloud instance is accessible via the VPN. As soon as I disconnect the VPN connection, the entries are synchronised.
Here are the logfiles.
