What's the problem 🤔

I'm running the Gluetun container on my Synology DS224+ NAS, and I keep encountering a DNS timeout issue that prevents the connection to various services and indexers such as Radarr, Sonarr, and Prowlarr from working.
Specifically, I am seeing the following errors in the logs:

ERROR [vpn] getting public IP address information: fetching information: Get "https://ipinfo.io/": dial tcp: lookup ipinfo.io on 1.1.1.1:53: read udp 10.5.0.2:33656->1.1.1.1:53: i/o timeout
...
ERROR [dns] cannot update filter block lists: dial tcp: lookup raw.githubusercontent.com on 1.1.1.1:53: read udp 10.5.0.2:38944->1.1.1.1:53: i/o timeout

This issue prevents Radarr, Sonarr, and Prowlarr from working properly, and I'm unable to download or search for content through these services. I do not use Jackett in my setup.

I've tried multiple solutions, including restarting the VPN adding dns manually but the problem persists.

and sometimes it shows me this log:

Suspect this is a dup of #2533 (read into the comments)

I keep encountering a DNS timeout issue that prevents the connection to various services and indexers such as Radarr, Sonarr, and Prowlarr from working.

It's the other way around. the dns is not working because the vpn is not working at all. You even tried with plaintext DNS which doesn't work. Check the link logged in your logs for possible solutions 🤷

Regarding Failed to load updated MTU of device that's a weird error coming from the Wireguard Go implementation (that part of the implementation is imported, so it's outside Gluetun's code). That's probably just Synology running some messed up weirdo kernel/system and sometimes it blows up a bit 😄

Sorry I cannot help more than this.
