Connection refused for prometheus exporters

Install & Config Docker
#1

I recently found out that the exporter I had been using somehow broke. I’m not sure whether this is because of a change in the jitsi docker image or something else. The last time I can confidently say it worked was in version 6173.

I previously used the jitsiexporter by xsteadfastx and also now tried the one by systemli, both of which get a Connection refused error when attempting to connect to the /colibri/stats path or any other monitoring API. I can use curl localhost:8888/colibri/stats and receive a result just fine. The exporters should have been in the correct docker network as well.

Here is my config:
exporter:

.env variables:

JVB_TCP_API_PORT=8080                                                           
JVB_TCP_MAPPED_API_PORT=8888   

# Optional properties for shutdown api                                          
COLIBRI_REST_ENABLED=true                                                       
SHUTDOWN_REST_ENABLED=true

Perhaps this turns out to be a stupid config error on my side.
Any help is appreciated.

U need to use the Docker internal hostname of the JVB instance and not localhost. I think http://jvb:8080/colibri/stats should work.
