Today I have backed up my database from a 12.4.1 virtual appliance and moved it to a 12.4.1 2019 server. When running 12.4.1 I managed to log in fine and make sure the import had worked. I then ran the upgrade to 12.6.0 (I could not see anything that said I needed to install a different version in the middle). Now I can't log onto the WHD at all.
http://localhost:8081/
Shows WHD screen and says it will be redirected.
localhost:8081/.../Helpdesk.woa
Shows the error - Can't reach this page

Has anybody else seen this and know if there is a solution? I have raised a ticket but I would like to try and get it up and running this weekend.
