@Samdani,

I hope you're doing good

It seems that some of the updates at the OS level they have broken the SSH connection between the SAS servers.

Can you please make sure you are able to SSH from all VA server and worker nodes without any password.

Please refer the below SAS knowledge base Article.

https://sas.service-now.com/kb?id=kb_article_view&sysparm_article=KB0036303

If above SAS KB Article doesn't help. Please raise a case with SAS Technical Support teams ( Drop a email to support@sas.com mail id)

And refer the below SAS Document for Start the SAS LASR Analytic Server Using SAS Visual Analytics
https://go.documentation.sas.com/doc/en/abmdref/8.42/n1f94ef1z58xb7n1stjfensbz6ky.htm

I Hope this helps
