I ran the Python script to debug but there the receiver seems to return just a 403 and nothing else:
AVR-X2500H.zip

# curl http://192.168.1.22:80/goform/
Error 403: Forbidden
Access Forbidden

I ran nmap to check if the port might have moved but it doesn't seem to be the case:

Starting Nmap 7.80 ( https://nmap.org ) at 2021-04-11 18:05 CEST
Nmap scan report for 192.168.1.22

80/tcp   open  http
111/tcp  open  rpcbind
8080/tcp open  http-proxy

Does anyone has a clue why the receiver is returning a 403? I had this working for a long time, but I think it broke with a firmware update.

@wilmardo have you tried power-cycling?
I have seen many cases where simple unplug power - wait 15 seconds - plug back in solved it for Marantz/Denon receivers.
Sometimes they just seem to freeze up their API.

@wilmardo have you tried power-cycling?

Thanks for the suggestion! I will try later today and keep you posted.

I also found these which might be related:

Sometimes the simplest of things fixes it. I did not try turning it off and on again.

Thanks @starkillerOG that indeed was the problem.

I feel stupid for not trying this earlier and living with it broken for a couple months :')
