I do not know if the problem persists when using vagrant. I do not get it anymore the way I commented on it.

Is this still a problem with the current implementation of H3 monitor?

Comment by Nicholas Clarke (Inactive) [ 17/Sep/17 ]

I get something similar when running the h3 monitor as a standalone context in a tomcat installation.

500 Internal server error...
