Hi There,

I was trying to login to the web UI today, and it wasn't responsive.  So I went to restart the linux server to clear out any issue.

Still not able to login.

I then used tpeap stop, and got an error that it failed and will try killing.

When I start, I get an JAVA error.

I removed omada and java8 and re-installed both.  I still get an error, although it seems to change slightly. 

I have tried multiple versions as well.

Attached the most recent one here.  Any ideas?
