This is most likely caused by either of the following:
The SQL Server uses an SSL connection and a valid client certificate is required to communicate with the SQL Server. This can be verified by checking the SQL Server logs in Event Viewer for the following error:
Encryption is required to connect to this server but the client library does not support encryption.The SQL server is running on a port that is not the default 1433. For example, binding to SQL server on 2431 can cause this problem.
ソリューション
Using SSL:
- First verify that the JIRA application server can both ping and telnet to the database server.
Disable the "Force Encryption On" setting on the MS SQL Server.
- Restart the JIRA application and monitor the
atlassian-jira.logto see if the connection is successful.
または
Install the certificate from the SQL Server into the keystore that the JIRA application uses as per our Connecting to SSL services.
Using a non-standard port:
