I get the above error on my server manager where SharePoint (2016 on prem) is running: (SQL 2014 and SP 2016 running on same server Windows 2012 R2)
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=2; handshake=60067;
Can it be that a SharePoint services in the IIS is started with the wrong account? How do I troubleshoot this?
