See

 * ssh(1)/sshd(8): the default IPQoS used by ssh/sshd has changed.
   They will now use DSCP AF21 for interactive traffic and CS1 for
   bulk.  For a detailed rationale, please see the commit message:
   https://cvsweb.openbsd.org/src/usr.bin/ssh/readconf.c#rev1.284

Change IPQoS

$ ssh <target> -oIPQoS=lowdelay
 or
$ ssh <target> -oIPQoS=none
 or
$ cat << EOS >> ~/.ssh/config
Host *
  IPQoS throughput
EOS
@dmaicher
Copy link 

Host *
  IPQoS throughput

fixes my issue

debug3: send packet: type 1
client_loop: send disconnect: Broken pipe

after moving from debian 10 to 11.

thanks 👍
