ssh_exchange_identifcation: Connection closed by remote host #8

Closed mhesselbarth closed 3 years ago

Not sure why this is happening from time to time on the server...after waiting for about a day always works again.

I got the same error using my google cloud from time to time, what fixed it was changing the ssh command to:

ssh -v -c aes256-ctr user@hpc

... for clustermq I think you can do that in ~/.ssh/config ... if that fixes your problem, we could include it in the guide.

I will try later...however, not sure how to test and reproduce the error because I have no idea why and when it is actually occurring

mhesselbarth commented 5 years ago

Not sure if related, sometimes also I get 

connect_to localhost port 6256: failed.
connect_to localhost port 6256: failed.
