java.net.SocketTimeoutException: Read timed outEnvironment
Tested on Bitbucket Data Center 8.9.5 and also applicable to other versions of Bitbucket Data Center.
Diagnosis
Perform the Test on Sonar Application UI and verify the result if it is failing or succeeding.
Validate whether Proxy parameters or environment variables are configured at Sonar Application configuration or relevant Load Balancer for Bitbucket endpoint.
Cause
This issue may arise if the Bitbucket Data Center endpoint is added to an incorrect environment variable NO_PROXY on the Sonar Application Server. The Sonar application does not recognize this configuration because the correct environment variable supported by the Sonar application is HTTP_NONPROXYHOSTS.
Solution
The issue should be resolved by replacing the NO_PROXY environment variable with the HTTP_NONPROXYHOSTS environment variable, including the Bitbucket endpoint, in the Sonar application.
