HI There,

We have 10 Linux server where 6 are running with SSH version 6.2 and working fine and rest 4 are running with SSH version 7.4 which is showing "SSH authentication or connection failure" error. Could you please advise how can fix this issue?

@amit_bt maybe the newer ones don't accept the simple credentials. Check this with your Linux admins - I'm quite sure the root cause is on their side.

Hi @amit_bt,

did you checked your SSH credentials with Check Credentials UI Action against these servers? You use SSH private key credentials, don't you? You need to check with your Unix experts, if maybe the type of key not working with ssh 7.4. I don't think that this is a ServiceNow issue - you need to talk to your Linux admins.

Thanks for reply @Daniel Borkowi1. We aren't using SSH private key, its just SSH credntial and it apply same credential to all of 10 linux hosts. Unfortunatialy 4 of them are upgraded SSH 7.4 where we are facing issue. rest 6 working fine.

Do we need to use SSH private key credentials?
