Hello @Hrishikesh Chinchalikar,Looks like facing issues with SSH key authentication on your SUSE server. Ensure that your new public key is correctly added to the ~/.ssh/authorized_keys file for the user blackdog, and check the permissions of the .ssh directory and the authorized_keys file to ensure they are set correctly.
Did you reset both the password and the SSH key at the portal or interface level?
Hello @Nikhil Duserla I reset the password and ssh key at the azure portal only.
For the below part I cannot confirm since I cannot access the server via any way. Even with azure cli password is not being accepted

hi there Hrishikesh,
thanks for posting this tricky ssh issue )
u can use the azure serial console as a lifesaver. its like a backdoor when ssh fails )) check this microsoft doc azure serial console. once there, u might need to tweak the sshd config to allow password auth temporarily. edit
find passwordauthentication and set it to 'yes'. then restart sshd with
. boom, u should be back in business!
this trick works on most linux distros, not just suse. worth looking into if u ever get stuck on other servers too. since u mentioned new keys didnt work... check the authorized_keys file on the server. sometimes permissions get messy. run
just to be safe. oh and make sure u copied the new public key correctly )) its easy to miss a character or two when pasting.
azure also lets u reset ssh keys directly from the portal if u want a gui way out. its under 'reset password' in the vm blade. microsoft really thought of everything huh?
if u still see 'no supported authentication methods', the issue might be selinux or apparmor blocking stuff. try putting them in permissive mode temporarily. but hey, thats more of a general linux thing, not just azure.
hope this helps,
Alex
Hello @Alex Burlachenko
Thank you for the kind information.
I tried for the azure cli despite my password is right it is not accepting the same.
I also done the password reset same issue
So unless password does not work this will be not possible to perform any action.
Do you have any further suggestion how to work on this ?
