sure, we would be glad to help you with that. However, we would need to investigate the issue to find out the cause and develop a solution. For that, we would need to check add-on and Bitbucket logs, could you please provide us with them? Repository-specific add-on logs reside at the following path on the Bitbucket server filesystem:
There are many svnmirror*.log files, please collect at least three latest.
Global add-on log and Bitbucket logs reside in the following directory:
Add-on logs are called svnmirror*.log, atlassian-bitbucket*.log files are Bitbucket server logs. Please collect at least three lates files of both kinds, too.
Also, I’d like to note that version 3.4.3 is very old, it’s been release in the middle of 2018, so I’d recommend to update it to latest 3.4.10.
