This issue has been observed after upgrading a Bitbucket instance that was running behind an outbound proxy to the 7.21.x version. While configuring the outbound proxy for Bitbucket server, it appears that there could be a typo or white space in one of the arguments. This is the root cause of the issue.
Solution
Recheck the outbound proxy configured as JVM_SUPPORT_RECOMMENDED_ARGS in the _start-webapp.sh file and remove if there are any unnecessary whites paces or typos in it. Restart Bitbucket for the changes to take effect.
