The hub received an http error response from an adapter.

The web server at the adapter is working well enough to send an error response, but has some problem that must be fixed by that adapter's admin.

If you are a user or an admin for a different shrine node please supply all of the details to the admin for the broken node.

This problem is often caused by a syntax error in the adapter site's shrine.conf. Tomcat started and can respond, but Shrine's servlet failed to start or crashed while responding to a request.
