read UDPv4 [EMSGSIZE Path-MTU=1358]: Message too large (code=90)

Running the docker container on a clean Debian 11 install, the download and startup process went normally. Got the client.ovpn file on my phone, imported connection without issue, and fired up immediately. On the terminal where the container is running I get nothing but these messages though:

I have done a quick google and it indicates this can be fixed with 'fragment' and 'mssfix' options but I am uncertain where/how to implement them for this setup. Also, I tested the MTU size for the docker host to the gateway system and it's 1472 (+28 = a proper 1500) so I'm not sure where the 1358 is coming from and erroring out.
