Very informative and very useful troubleshooting scenarios. also please replicate following issue and try to troubleshoot this scenarios. (due to its nature of the error this has multiple scenarios in itsetlf) Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=0; handshake=14999; (Microsoft SQL Server, Error: -2)

Hi, I am facing a issue on AOAG. we have 3 nodes server and 2 are in synchronous commit and another is in asynchronous commit mode in the weekend the 3rd node (Asynchronous) is terminated from primary replica for few seconds and after that it will get connected automatically it's on AWS EC2 instances i am not able to find the solution could you please help me out for this issue?

[@vinayak717]

If my AG is Asynchronous commit & fail over mode is manual and if my both Server is restarted what happens to AG is my AG will be healthy after restart

[@vamsychiranjeevi9619]

if it is graceful restart then the databases will need to go through crash recovery for primary and secondary replicas. Post that the databases will come online on primary and on secondary if not we need to resume them
