Ubuntu wsl 2 suddenly can only pull from git ( both github and gitlab ) when I use a vpn ( any vpn, a commercial one like privatevpn or OpenVPN )

This is really weird, it's three days that I am not able to pull from any git repo.
If I use git trace I see that this hangs

> 12:08:48.904172 run-command.c:655 trace: run_command: unset
> GIT_PREFIX; GIT_PROTOCOL=version=2 ssh -o SendEnv=GIT_PROTOCOL
> git@gitlab.com 'git-upload-pack '''gitrepo.git'''

but ping works

PING gitlab.com (172.65.251.78) 56(84) bytes of data. 64 bytes from
172.65.251.78 (172.65.251.78): icmp_seq=1 ttl=57 time=18.8 ms 64 bytes from 172.65.251.78 (172.65.251.78): icmp_seq=2 ttl=57 time=18.3 ms

The weird thing is that if I am inside ANY vpn in windows, I have a commercial VPN and a company VPN ( for a different company, unrelated to this repo ) and if I turn them on, everything works!I am in Spain, so no strange filtering.

My resolv.conf is

# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /># [network]
# generateResolvConf = false
nameserver 172.17.0.1

and the ipconfig for the wsl is

any idea of what is happening? I tried to reset everything, uninstall everything, upgrade all packages, nothing changed

EDIT I also ran

❯ tcptraceroute gitlab.com 22

So the issue was with ssh.

By adding this into the top of my ~/.ssh/config file I got if fixed for every git and ssh operations:

Host *
  IPQoS=none
