Hello Peeps, Recently I was configuring vRA 7.4 at a customer’s place and came across an issue where the vRA appliance tries to talk to the external SQL server and fails with an error.
Here is the error:
After digging into the logs on both vRA and on the SQL server, here is what was determined as the issue
The SQL server has TLS 1.0 disabled and the vRA appliance was trying to communicate to the SQL server using TLS 1.0 instead of TLS 1.2 as the client has disabled TLS 1.0 on all its windows servers.
Troubleshooting steps tried:
Tried enabling TLS 1.0 and its Ciphers on the SQL server with no success
Checked with the Firewall team and they said that there is no firewall between the vRA appliance and the SQL server
Tried this in a different environment and it worked fine, just doesn’t work in this particular environment.
Looks like the issue was with the SQL server and its Service Pack. SQL Server 2012 needs SP3 or higher to accept TLS 1.2 protocol. As soon as I upgraded my SQL server to SQL 2012 SP4, the communication worked fine and the vRA appliance was able to talk to the SQL server!!
Hope this helps in case you come across this issue.
