Uanble to update Confluence 8.5.23 to 9.2.5

Christoph June 19, 2025

Hello, I wanted to update our Confluence production instance from version 8.5.23 to version 9.2.3. After the update everything looks ok. But when I click on login in the top right corner to get to the login page, the following error is displayed:2025-06-18 21_14_53-Oops - an error has occurred - Confluence – Mozilla Firefox.png

We still have a Confluence test instance. I have also updated this to version 9.2.3. The test instance does not have the problem. The login page opens without any problems.

The test instance uses only the internal directory for authentication and the production instance uses Active Directory on first position and the internal directory of Confluence onn second position. Can the problem be caused by the configured Active Directory?
Otherwise, the test and production instances differ in that not both instances have the same plugins from the marketplace installed.

Currently our Confluence prod instance is running again, because I have reverted the previously created snapshot in vCenter and the previously created data dump in the Orcale database. Nevertheless, I have to update to 9.2.3 at some point.


Unfortunately, I did not save the Confluence log file before restore.

  • What steps did you follow for the upgrade?
  • Did you try to upgrade to 9.0.0 first? 
  • What are you seeing in the application logs?

Best,

Fadoua
