hi,

i just tried to install omada SDN Controller 4.4.4. but i wasn't able to finish the initial web-setup. I always get "gerneral error" when trying to finish the update.

meanwhile i tried 4.4.3 (same result) as well as now 4.1.5. openjdk-8 is installed and mongodb 3.6.8, and overall the system process starts up fine. only the web setup fails.

any idea?

in server.logs i get this error message:
