Hi, I have implemented PMM server(docker installation) and it is behind haproxy. If I access the dashboard I can see the data and graphs. Prometheus queries work well. However when I put it behind haproxy some parts of dashboard is broken with Request Error. I go to query inspector and debug it.

With the server IP (like this [URL][https://192.168.1.123/graph/[/URL]](https://192.168.1.123/graph/%5B/URL%5D)) the query works just fine.

However behind haproxy ([URL][https://pmmdashboard.mydomain.local/graph[/URL]](https://pmmdashboard.mydomain.local/graph%5B/URL%5D)) the query fails with Bad request Your browser sent an invalid request.

Is there any particular setting for haproxy ?

Thanks and Regards,
