Cant access WebUI with Sidecar Dispatcher enabled

[IWShady]

I dont know that its a bug or something with my particular setup. I have the LibreNMS, Redis, and rrdcached installed and all seem to be working together. However, I can only reach the WebUI if the Sidecar Dispatcher is disabled. I have the install behind an NGINX proxy server so perhaps I just need to adjust something. Any help would be greatly appreciated.

Behaviour

When enabling the sidecar dispatcher the WebUI becomes unreachable. Both by direct IP and by name. The system appears to be working though as I can disable the sidecar and login and I see my one test device has graphed usage.

Steps to reproduce this issue

1. Spin up new LibreNMS install
2. Enable Sidecar Dispatcher
3. Try to load WebUI

Expected behaviour

WebUI should load with dispatcher enabled.

Actual behaviour

With sidecar enabled the WebUI is no longer accessible. Trying to connect by IP gives "Problem loading this page". By name it is behind an NGINX p-roxy server and it gives a 502 Bad Gateway.

[Gunsrude]

I had this issue when I was setting up shared environment variables. It was because SIDECAR_DISPATCHER and DISPATCHER_NODE_ID were defined on both containers for me.

[murrant]

SIDECAR_DISPATCHER does not run a web server (or other services) it only runs the dispatcher.
