Exposing Hydra to the internet and using reverse proxies
If you want your Hydra instance to be accessible from other computers I strongly recommend putting it behind a basic auth protected reverse proxy (e.g. Apache or nginx).
Make sure to include all the important headers (x-forwarded-to, x-forwarded-proto and host or x-forwarded-host). Also X-Forwarded-For to get the actual IPs of callers and x-forwarded-port if the port is not 80 or 443.
It also works best if you use the same URL base in the reverse proxy and for hydra (i.e. /nzbhydra2 as the location in nginx and as URL base in the hydra config).
<VirtualHost *:443>
#If you use a different port make sure to include it in the X-Forwarded-Host header or set X-Forwarded-Port

Assuming you have configured the ingress with HTTPS (like in the example above) but are proxying requests to Nzbhydra in your docker / kubernetes cluster which are just listening on HTTP. You will see '400 bad request' errors. You need to tell Traefik to forward the x-forwarded- headers to the destination:
additionalArguments:
- --entryPoints.web.proxyProtocol.insecure
- --entryPoints.web.forwardedHeaders.insecure
In the main settings set your "URL base" to "/nzbhydra2" if you used a path in the reverse proxy. Leave it empty if you don't (for example "ProxyPass / http://127.0.0.1:5076/", which is unusual).
If you have selected to add NZBs to downloaders by sending links make sure that you call Hydra using an address that is reachable by the downloader.
