Errors and instability under VPN

[litio2001]

When I launch the container connected under VPN (using Gluetun container) in the acelink log I see many errors that are not shown when I do NOT use VPN.

I Paste container log acelink: *(I have replaced the link ID with XXXX for privacy)

These errors when not connected by VPN are not displayed. However, even with these errors the playback usually works, but when many errors begin to appear it begins to be unstable. Since it is a paid VPN, I can configure it by removing the security filters (ad blocking, etc.), activating NAT and port forwarding:

More data: 1- I use paid ProtonVPN (Wireguard protocol). 2- The acelink container is associated with the Gluetun container network. 3- My host system is a Synology DS920+

I paste my docker compose (I use portainer):
