I have registered a remote server and then created a cluster. If I add both the local instance and the remote server, when I visit the configured website I get this error: The page cannot be displayed because an internal server error has occurred." However, if I remove the remote server so only the local server is in the cluster the site works fine. ALSO, if I remove the local server and only have the remote server in the cluster the site works fine. It's only when both are in does it fail. In the isapi redirect log I see this:
[Fri Jan 19 20:46:36.099 2018] [1184:9128] [debug] ajp_close_endpoint::jk_ajp_common.c (921): (site2) closing endpoint with socket -1 (socket shutdown)

Any ideas what it could be? I am pretty certain I have everything correct.
