In case you migrated from Jira Cloud to the self-hosted version your server id probably got corrupted. You can revert this by searching your Jira logs for the ID and manually change it in the database.
- Download a support ZIP from the Jira
- Stop the Jira server
grep -r "Installation Type" -C 5 .inside of the extracted support ZIP
- You can find now a previous Server ID by looking though the output
- Log into your database and update your Server ID:
UPDATE propertystring SET propertyvalue = 'XXXX-XXXX-XXXX-XXXX' where id = (select id from propertystring where id in (select id from propertyentry where PROPERTY_KEY='jira.sid.key'));
- Star Jira again!
You should have a new server id now.
