Nest source encounters 409 and retry attempts hit 429 rate-limit

Open trvrnrth opened this issue 1 year ago • 5 comments

I have a nest hello gen 1 wired doorbell source which, after some time experiences a 409 response:

error="streams: nest: wrong status: 409 Conflict, exec: rtsp://127.0.0.1:8554/front_door?audio: Invalid data found when processing input\n" stream=front_door

It appears that there is no back-off on attempts to re-connect so these are then rate-limited:

error="streams: nest: wrong status: 429 Too Many Requests, exec: rtsp://127.0.0.1:8554/front_door?audio: Invalid data found when processing input\n" stream=front_door

The full error message grabbed from the Device Access Sample App at this time is:

{
  "error": {
    "code": 429,
    "message": "Rate limited for the GenerateWebRtcStream API for the user.",
    "status": "RESOURCE_EXHAUSTED"
  }
}

At this point a restart is not sufficient to re-connect. go2rtc must be stopped for some time to allow the rate limit to "clear" before being started again (in my case this is a case of manually stopping, waiting a few minutes then starting the HA Frigate add-on).

I am unclear what causes the initial 409 conflict response, but implementing a back-off on at least the 429 response would be good. I guess it might make sense to just back-off on any error which would lessen the chance of hitting the rate limit in the first place.

Here is a full extract from the logs at the time of last failure:

I had a bit of time to do some local debugging of this and realised I'd not provided my stream config in the issue above:

streams:
  front_door:
    - nest:?client_id=REDACTED&client_secret=REDACTED&device_id=REDACTED&project_id=REDACTED&refresh_token=REDACTED
    - "ffmpeg:front_door#audio=aac

The testing I've done suggests that the fixed 5 second retry I'm seeing stems from the ffmpeg audio transcode I have in place so I am currently testing with a 60 second timeout as follows to see if this helps:

      - "ffmpeg:front_door#audio=aac#input=-fflags nobuffer -flags low_delay -timeout 60000000 -user_agent go2rtc/ffmpeg -rtsp_flags prefer_tcp -i {input}"

Did this ever get resolved? I'm trying this inn the go2rtc addon in the frigate docker container and can't seem to get my nest cam working?

softcoder avatar Nov 12 '24 03:11 softcoder

Adjusting the timeouts (in both the ffmpeg transcode and also externally in frigate) mitigates the 429 rate limiting, however I am still seeing the stream getting stuck receiving 409 responses (now at 60 second intervals).

At this time I can replicate the responses in the Device Access Sample App as follows:

{
  "error": {
    "code": 409,
    "message": "Failed to retrieve answer SDP due to timeout, please try again.",
    "status": "ABORTED"
  }
}

Restarting appears to be sufficient to resolve whatever the underlying issue is, although on my last restart I did see a single 409 response before the stream started working again.

@AlexxIT may I know that if I want to add this exponential backoff ability, or maybe even restart the nest subscription, which file should I start looking into?

Hi, @AlexxIT any update about this issue?

Thanks !

I don't use Nest. Can't fix it myself.

AlexxIT avatar Feb 20 '25 10:02 AlexxIT

I hit this quite often unfortunately and often have to remote in, turn off my container for 15 minutes, turn it back on to workaround rate limit issues. I end up with nest wrong status 429 - too many requests. I thought I would have addressed it with -timeout flag but 6000000 doesn't seem to do it.

Just want to share a bit progress on this. I believe somehow I have the retry implemented. I will test for a few more days and submit PR. Image Image

I bumped into this a couple days ago. The exact same go2rtc.yaml config, with the exact same nest: URL with the same magic tokens in it, fails to bring up any feed on frigate (and indeed fails to show any stream if you expose port 1984 in the frigate container), but works when ran from a standalone go2rtc binary, or a go2rtc home assistant add-on. If you fiddle with frigate configuration to point at an external go2rtc service, it is possible to have your nest cams working within frigate.

Except I'm having an issue where the camera feed stops working after 5 minutes and there's nothing in the logs (trace level) to account for that (yes, I did grab a fresh refresh_token, didn't help), which is what sent me searching for clues 'round these parts.

Thanks, I see this was merged a few days ago (https://github.com/AlexxIT/go2rtc/pull/1669), so now we just wait for next go2rtc release, then for Frigate to pick that up - or run a custom version sooner (https://docs.frigate.video/configuration/advanced/#custom-go2rtc-version)

astyrrian1 avatar May 06 '25 15:05 astyrrian1

I am testing this out now via nightly build and custom binary in frigate. So far working really well. Thank you!

Just to add this is working well for me too. Only tested for 5 minutes but I can already tell the difference

I am encountering this issue as well with go2rtc v1.9.9 and my Nest cameras. Excerpt from the logs:

I have 3 Nest cameras in total, the Nest wired doorbell seemed to work most of the time but is now also giving time outs. The Nest outdoor camera has never worked (always timing out). And my Nest indoor camera is 50-50 working and not working.

Any way of solving this?
