I’ve seen similar errors before, didn’t make good notes on how it was resolved.. so here are a couple of items.
1 – nano ~/.ssh/config and set the connection parameters for each server you often connect to using the example below: – there are other items you can provide but this is all I needed to login!
Host myserver Hostname my-linux-host.local User angeln Port 22 Ciphers 3des-cbc

-v Verbose mode. Causes ssh to print debugging messages about
its progress. This is helpful in debugging connection,
authentication, and configuration problems. Multiple -v
options increase the verbosity. The maximum is 3
