Running the software controoler controlling 2 EAP 245 v3 access points for home use.

Recently noticed fast roaming was not working so went to check the controllor.

Had not touched the controller in months but when I check I found it had stopped working.

When I try to restart I see the following in server.log

2020-12-31 20:26:34 [main] [INFO]-[ContextHandler.java:2040] - Initializing Spring FrameworkServlet 'springMVC'
2020-12-31 20:26:34 [main] [WARN]-[SourceFile:403] - Site Default to create is already existed.
2020-12-31 20:26:34 [main] [ERROR]-[SourceFile:120] - Failed to init site
2020-12-31 20:26:34 [main] [ERROR]-[SourceFile:17] - Failed to start omada controller, going to exit
 

In the past when this had worked it logged the following

2020-07-07 04:18:07 [main] [INFO]-[ContextHandler.java:2040] - Initializing Spring FrameworkServlet 'springMVC'
2020-07-07 04:18:07 [main] [INFO]-[SourceFile:152] - no need to compatible db.
2020-07-07 04:18:07 [main] [INFO]-[SourceFile:20] - Omada Controller started
 

Any thoughts on the best way to resolve. I could try updating but would prefere to get it back to a working setup before introducing a new version.
