How to debug go2rtc | Home Assistant | Page 1

Hey all, I need to get access to the debug console of go2rtc to get data for a bug ticket, but I can't figure it out. I've got

default_config:
  
go2rtc:
    debug_ui: true

in my configuration.yaml, and if I understand the documentation on the home asssistant website correctly, that should give me a debug UI on http://homeassistant:11984 but I don't get anything.

What am I doing wrong here? Can somebody help me out?

What URL do you use to connect to the HA frontend?

#

And maybe elaborate on 'don't get anything'

undone temple Jun 4, 2025, 8:11 PM

#

If I want to connect to ha frontend, I navigate to http://homeassistant:8123. By "I don't get anything" I mean that in the browser I get a refused connection, and when I nmap the server, it shows the port as closed.

#

Port 18555 seems open, but it doesn't accept connections either.

#

Did you restart HA after editing the config?

undone temple Jun 4, 2025, 8:19 PM

#

Yes I did. I can try again if you would like me to.

#

So my assumption that a web ui should exist on port 11984, and what I put into the config file are basically correct then?

#

I've restarted again and the situation hasn't changed.

violet vector Jun 4, 2025, 8:21 PM

#

You're using HAOS then?

undone temple Jun 4, 2025, 8:21 PM

#

Yes I do.

#

Should I try restarting the OS then?

violet vector Jun 4, 2025, 8:22 PM

#

I doubt that would be necessary

#

But feel free to try

undone temple Jun 4, 2025, 8:22 PM

#

That was my assumption also, but I guess it can't hurt to try.

#

Ok, server has rebooted, and the situation is basically the same.

I already had it enabled in my container install and it works for me:

#

What if you use the HA IP address instead of homeassistant host name? The default URL is http://homeassistant.local:8123/, not sure if you have something else going on there.

#

I'm not an HAOS user, but I have a VM for testing. I just started it, configured go2rtc the same way and after a restart the UI is available.

Well, that's nice for you, but how does that help me figure it out?

violet vector What if you use the HA IP address instead of `homeassistant` host name? The defa...

I tried with the IP address, with the same result. Didn't really expect anything else, since without https, the dns name really is little more than an alias for the IP.

violet vector Jun 4, 2025, 9:11 PM

#

Depends on what homeassistant is resolving to.

undone temple Jun 4, 2025, 9:13 PM

#

🤷‍♂️ It's really just mDNS. There's no CNAME or anything involved really.

violet vector Jun 4, 2025, 9:13 PM

#

Ok, wasn't sure since it's not the default.

undone temple Jun 4, 2025, 9:14 PM

#

How is it not the default? As far as I know, it is. I sure didn't fiddle with it.

violet vector Jun 4, 2025, 9:14 PM

#

http://homeassistant.local:8123/ is the default AFAIK

#

That's what my instance comes up with and is in the docs.

#

So just wasn't sure if you had something else configured in your setup.

undone temple Jun 4, 2025, 9:15 PM

#

the .local postfix is basically just an optional clarification in case you have an external search domain set.

#

If your search domain were set to mydomain.com and you had a server homeassistant.mydomain.com, you'd need it, but as long as you don't have a server of the same name in your search path, it's optional.

violet vector Jun 4, 2025, 9:17 PM

#

Not the case for my PC, but ok.

#

Doesn't seem to be the issue anyways.

undone temple Jun 4, 2025, 9:17 PM

#

Definitely not.

#

Is there any way I can remove and reinstall go2rtc? Something seems to have gone wrong with it at some point.

violet vector Jun 4, 2025, 9:18 PM

#

It's included in the HA container, not really anything to install

undone temple Jun 4, 2025, 9:19 PM

#

Well, it seems to be running in principle, otherwise the 11855 port would not be open.

#

It's just not behaving the way it should.

violet vector Jun 4, 2025, 9:19 PM

#

All the debug_ui settings does is configure go2rtc to listen on all ip addresses

undone temple Jun 4, 2025, 9:20 PM

#

Which may very well be the root cause of my problem

#

maybe the internal routing of the container is snoggered?

violet vector Jun 4, 2025, 9:21 PM

#

➜  / docker exec -it 523f77a0a5f7 sh -c "cat /tmp/go2rtc*"  
# This file is managed by Home Assistant
# Do not edit it manually

api:
  listen: ":11984"

rtsp:
  listen: "127.0.0.1:18554"

webrtc:
  listen: ":18555/tcp"
  ice_servers: []

#

can't really do that on haos, can I?

violet vector Jun 4, 2025, 9:22 PM

#

I did that from the community ssh addon

#

the HA container uses host networking

#

Also I can type login from the console to get to a shell, and ss -nltp shows it listening

undone temple Jun 4, 2025, 9:25 PM

#

I actually have that addon installed, but I thought it places me inside the container? It doesn't seem to know the docker command

violet vector Jun 4, 2025, 9:25 PM

#

Protected mode must be turned off to use docker

undone temple Jun 4, 2025, 9:26 PM

#

How do I do that?

violet vector Jun 4, 2025, 9:26 PM

#

go to the add-ons settings and turn it off

#

undone temple Jun 4, 2025, 9:35 PM

#

Hm, It would appear the ssh port on my ha server isn't open...

violet vector Jun 4, 2025, 9:36 PM

#

it's usually not

undone temple Jun 4, 2025, 9:36 PM

#

Also it says port 22 is deactivated in the addon settings.

violet vector Jun 4, 2025, 9:37 PM

#

it would not be enabled unless you configured the add-on for it

undone temple Jun 4, 2025, 9:37 PM

#

It seems I don't quite follow what you are doing here. Are you using the web console or an ssh client to connect?

violet vector Jun 4, 2025, 9:37 PM

#

I used the host console

undone temple Jun 4, 2025, 9:37 PM

#

Oh you connected a monitor and a keyboard!

violet vector Jun 4, 2025, 9:38 PM

#

technically, yes. it's a VM.

undone temple Jun 4, 2025, 9:38 PM

#

Well I'd like to avoid that if at all possible, because it would require a gargantuan logistical effort to set that up.

violet vector Jun 4, 2025, 9:39 PM

#

You can enable SSH for debugging, but it's not really a simple process either. https://developers.home-assistant.io/docs/operating-system/debugging

undone temple Jun 4, 2025, 9:42 PM

#

Why can't that bloody OS just conform to normal unix system administration standards?! If I wanted a welded-shut box, I'd buy commercial and drop it on the sales rep's toes if it behaved as eratically as HA does at times!

#

Let's put a bookmark here, I need a good 8 hours of sleep to recharge my motivation and frustration tolerance.

violet vector Jun 4, 2025, 9:46 PM

#

I think it's designed to be a "welded-shut box"

#

the debug option is available, so

#

don't forget to check the HA logs as well, in case anything obvious has been missed, such as go2rtc errors.

undone temple Jun 4, 2025, 9:48 PM

#

If it's designed like a welded-shut box, it should work like one - flawlessly. If it constantly creates problems, denying people the opportunity to fix them without jumping through a million hoops will not make you a lot of friends.

#

I'm telling you, I'm THIS close to chucking the whole thing in the bin and buy something off the shelf...

#

Yes, I did check the HA logs, nothing related to go2rtc in there.
