ANSWERED AirVPN with Gluetun docker and WireGuard

[Alandil 0]

Hi,
I have a recurring error that seems to concern a reception problem on the part of cloudflare.com
Here it is: 
[healthcheck] unhealthy: dialing: dial tcp4: lookup cloudflare.com: i/o timeout
This causes an unhealthy and a restart of the container, and everything that follows crashes.
According to the container designer, the cause can only be external to the container.
So I'm asking you to help me find a solution...
Thanks in advance!

Was this resolved? I'm having the same issues with a similar configuration. I'm running a docker with multiple containers behind a gluetun wireguard vpn (airvpn,) and I'm observing frequent i/o timeouts that are causing long dropouts while wireguard attempts to reconnect.

Hello!

Please check this. Although the starting problem was different, you could get a mitigation with an identical approach:
On top of all of the above, make sure you test different WireGuard interface MTU, starting from the minimum size of 1280 bytes. The correct MTU may also stabilize the connection.

Kind regards
