Morning Seth,

You hit the right key! Adding to ssh_config:


    IPQoS none


now it works correctly:


acs@lsp-022:~$ ssh -T g...@github.com
Hi acs! You've successfully authenticated, but GitHub does not provide shell 
access.


With the default value (lowdelay) it just not connect.

With reliability it works, but with  throughput, it does not.

It is strange that this is a problem with my network. It works in other
laptops with previous versions of Ubuntu.

So my guess is that it is related just with the ssh client version.

If you need that I do more testing just ask for it.

Thank you very much.

Title:
  Can not ssh to github.com or gitlab.com when upgrading to 22.04

Status in openssh package in Ubuntu:
  Incomplete

Bug description:
  Dear all,

  After the upgrading to Ubuntu 22.04 I can not use git over ssh.

  The best way to reproduce the error is:

  ```
  acs@lsp-022:~$ ssh -vT g...@github.com
  OpenSSH_8.9p1 Ubuntu-3, OpenSSL 3.0.2 15 Mar 2022
  debug1: Reading configuration data /etc/ssh/ssh_config
  debug1: /etc/ssh/ssh_config line 19: include /etc/ssh/ssh_config.d/*.conf 
matched no files
  debug1: /etc/ssh/ssh_config line 21: Applying options for *
  debug1: Connecting to github.com [140.82.121.4] port 22.
  debug1: connect to address 140.82.121.4 port 22: Connection timed out
  ```

  Before the upgrading I can connect correctly with:

  ```
  ssh -vT g...@github.com
  OpenSSH_8.2p1 Ubuntu-4ubuntu0.4, OpenSSL 1.1.1f  31 Mar 2020
  debug1: Reading configuration data /etc/ssh/ssh_config
  debug1: /etc/ssh/ssh_config line 21: include /etc/ssh/ssh_config.d/*.conf 
matched no files
  debug1: /etc/ssh/ssh_config line 23: Applying options for *
  debug1: Connecting to github.com [140.82.121.4] port 22.
  debug1: Connection established
  ```

  The same issue is happening with gitlab.com.

  Probably it is related with the OpenSSL version.

  Cheers!
