Confluence Build Numbers Match but Confluence Won't Start

[europoint]

I updated my Docker container and I am getting the following error:

Confluence will not start up because the build number in the home directory [8501] is newer than the Confluence build number [8401].

However, my confluence.cfg.xml has the following:

<buildNumber>8501</buildNumber>

 And the latest value in the CONFVERSION table is also 8501 (Install date: 2020-06-08 23:47:41).

The log file shows the following message:

2020-07-08 08:32:44,271 INFO [Catalina-utility-2] [com.atlassian.confluence.lifecycle] contextInitialized Starting Confluence 7.4.1 [build 8401 based on commit hash 758836457240a7983be3b3db3463da30107b780e] - synchrony version 3.1.0-master-022ca438

Where else is Confluence looking to determine that the build number is 8401 and not 8501?

It looks like my Docker container environment variables weren't updating, so I deleted the container and Image and redeployed my stack, which then ensured that the correct build was communicated through to the Confluence.

The database contains the build number of the current data set.

You'll want to go back to a Confluence version that matches the database and upgrade it.
