   I'm seeing errors like this on my RasPiOS Pi4 ssh client host:   
      
   Connection closed by remote host   
   Corrupted MAC on input.   
   ssh_dispatch_run_fatal: Connection to 50.1.20.29 port 22:   
   message authentication code incorrect   
      
   They show up after a successful ssh login, usually shortly after,   
   sometimes never. The connection can be re-started, but the error   
   persists even after rebooting the remote host.   
      
   It happens with some hosts and not others, I'm trying to figure   
   out if it's my RasPiOS workstation or the clients (FreeBSD)   
   reporting  the error. The IP number shown is of the remote host,   
   but which MAC is being complained about and by whom I can't tell.   
      
   If anybody's seen this or has a clue please post!   
      
   Thanks for reading,
