In one of my Always on Environments, I used to get the below error daily at a particular time, and when I log in to the environment to check the status it is showing everything looks good. My always-on Environment is not multi-subnet and it is a normal environment.

A connection for availability group 'ListerNameHere' from availability replica 'PrimaryReplicaNameHere' with id  [996F8E9F-1808-4606-9D69-7614F6E7CDE7] to 'SecondaryReplicaNameHere' with id [417DDEB3-5F9A-42F2-9906-5E577AA3BA69] has been successfully established. This is an informational message only. No user action is required.

And when i check the event viewer i used to get the below error on each database that are participating in Always on Availability groups.


I am using Microsoft SQL Server 2014(SP3-CU-GDR), Microsoft Enterprise Edition. When I google this error I found very few blogs, and they are mentioned to check Network connectivity, port connectivity, the firewall in my case the issue resolved after changing the timeout from 10 to 60 in the Always-on Availability groups
