Server returned HTTP status 406 Not Acceptable

Hello,

I’m trying to use Prometheus for monitoring usage of my shinyproxy container.
I have followed all the instructions in https://www.shinyproxy.io/documentation/usage-statistics/#configuration-2

However, when I open Prometheus, the state of my shinyproxy endpoint is Down and I get the following error: server returned HTTP status 406 Not Acceptable

Does anyone know what’s going on?

Please let me know if you’d need me to share anything else if it will help.

Thank you
