Wrong response on DESCRIBE (301 Moved Permanently is not followed)
I have a setup where if a camera is offline a 301 response is provided as a fallback, but it seems go2rtc has trouble following the redirect. The version is 1.9.4, these are the logs of the issue:

I found a similar issue (https://github.com/AlexxIT/go2rtc/issues/565) but it was fixed in 1.7.0.
I have this issue with a Tapo TC70 as well. HD stream is sometimes unavailable, and doesn't fall back to the non-HD one. I'm using version 1.9.7 on HA.
