How to solve this problem. In the previous migration, we also directly packaged the container to decompress and run on the new server without any problems. I don't know what the problem is this time.

I found this article where the atlassian reps provide an explanation: <https://community.atlassian.com/t5/Jira-questions/What-does-this-unexpected-EOF-error-means/qaq-p/919674>

I hope this helps.
