Question

help - intermitent failures connecting to workers on `cloudretro` example on AWS + EKS + ALB

calexandre opened this issue a year ago · 16 comments

I've been building the cloudretro example for a while on multiple kubernetes distributions without issues!
Now I'm trying to run this example on AWS setup (EKS + Fargate + ALB) and I'm getting some intermitent errors:

Sometimes I'm able to connect to the workers, and other times I have timeouts
I suspect it has something to do with the ICE candidates that are reported on the application - I've posted evidences below on the differences

Versions:

I'm using both stunner and stunner-gateway-operator versions 0.16.0 (chart and app)
EKS 1.27

Based on the information below, what is the culprit here?
Is there anything I can tweak server side to facilitate this discovery and ensure a successful connection on first attempt?

error attempt

The following errors were captured on the browser using hte Developer tools.

Usually when I first reach the coordinator, I usually get the error [rtcp] ice gathering was aborted due to timeout 2000ms.
I notice that only one user candidate 02895ab7-03e2-4f4a-9afe-daa99822e2d5.local gets reported and its not reachable (and should not be!)

Error console:

Hello there,

The really first thing that comes to my mind, that this specific part (collecting ICE candidates) happens clientside, and there were many known bugs about chromium sometimes taking MUCH longer to gather candidates.

Before I get deeper, could you please confirm that the same issue happens from other clients/different browsers?

Answer 3 · 2023-10-09T13:38:37.000Z

O confirmed it is happening on:

edge
chrome

I've tried multiple times on firefox and was not able to reproduce the issue (it always works).

Based on this, I think your assumption regarding chromium based browsers might be true...

Scratch this...
I was able to reproduce this on firefox aswell..But note that it only started happening after a couple of tries..

Any hints?

Answer 5 · 2023-10-09T14:02:02.000Z

Do you think you can gather the corresponding logs from STUNner, preferably at a higher loglevel (say, all:TRACE)? I'm not at all saying that this is not a STUNner bug, but (to my surprise) we see very few similar annoying browser compatibility issues with the other demos...

Answer 6 · 2023-10-09T14:56:16.000Z

Sure!

I managed activate verbose mode on the client console. I also persisted the logs over the multiple retries so that you can have a proper timeline.

Console logs captured on Chrome

On the stunnerd side,

I need instructions on how to change the STUNNER_LOGLEVEL using the helm approach (I only found that for standalone mode)
the server only wrote INFO logs when the client successfully connected.

Answer 7 · 2023-10-09T16:28:25.000Z

I was able to activate the TRACE logs on stunner.

there's no activity whatsoever during the retry attempts, meaning that this is something happening on the client side.

Stunner logs with TRACE enabled:

Thanks a lot, this indeed seems like a client problem. I'm wondering whether the empty messages received from the coordinator may be the origin of the problem:

socket.js?v=4:54 [ws] <- message ''  {id: '', data: '', room_id: '', player_index: 0, packet_id: '', …}
socket.js?v=4:54 [ws] <- message ''  {id: '', data: '', room_id: '', player_index: 0, packet_id: '', …}
rtcp.js?v=4:108 [rtcp] ice gathering was aborted due to timeout 2000ms

I guess the client should receive the ICE candidates from the server in these messages, but for some reason the messages are empty.

That being said, it seems that there actually exists a candidate pair that should work (at least for the 3rd attempt):

socket.js?v=4:54 [ws] <- message 'ice_candidate'  {id: 'ice_candidate', data: 'eyJjYW5kaWRhdGUiOiJjYW5kaWRhdGU6MjEyODg1ODE2NiAxIH…pbmVJbmRleCI6MCwidXNlcm5hbWVGcmFnbWVudCI6bnVsbH0=', room_id: '', player_index: 0, packet_id: '65d1dfd1-964f-48a7-bf71-a2b38f772dc5', …}
...
rtcp.js?v=4:179 [rtcp] add candidate: {"candidate":"candidate:2128858166 1 udp 2130706431 10.0.30.202 35636 typ host","sdpMid":"","sdpMLineIndex":0,"usernameFragment":null}
...
rtcp.js?v=4:100 [rtcp] user candidate: {"candidate":"candidate:3339608042 1 udp 33562623 10.0.22.42 46610 typ relay raddr 89.180.168.100 rport 42127 generation 0 ufrag evwk network-cost 999","sdpMid":"0","sdpMLineIndex":0,"usernameFragment":"evwk"}

I'm wondering why this doesn't work (not sure whether the "usernameFragment":null on the received candidate is an error).

@bbalint105 let me know if you have time (and motivation) to debug this sometime

I'm wondering why this doesn't work (not sure whether the "usernameFragment":null on the received candidate is an error).

Which component responds with the available candidates? Is it the stunnerd workload?

Answer 11 · 2023-10-10T10:33:42.000Z

I looked into it, and it could be something with the CloudRetro code.
For first look, it seems like they already fixed it, but the branch I provided is ~170 changes behind, not to talk about they changed the entire handling of ICE servers as well (thus, there would be the need to redo/re-plan the whole demo).

I asked the devs if they know anything about this particular issue, and if it was fixed already.

Answer 12 · 2023-10-10T10:47:25.000Z

Any plans to redo the demo?

Answer 13 · 2023-10-10T12:33:18.000Z

If their answer is straightforwward, and I don't have to test and redo everything that would be nice.

Answer 14 · 2023-10-10T15:32:06.000Z

Followup:
There were no such issues with CloudRetro so far, so there are some kind of sneaky bugs in-between.

Answer 15 · 2023-10-11T09:45:05.000Z

First of all, thank you for debugging the issue @bbalint105

I already tried to debug the client's code, but I have not been able to pinpoint the problem...

Some questions:

Were you able to reproduce it on your end?
Can you confirm that is something on the client and not on the server side?
How is the discovery of ICE candidates performed? I'm trying to understand how those clients in the form <guid>.local appear on the ICE candidates list...

Answer 16 · 2024-02-01T18:42:02.000Z

Closing this for now as it seems like a CloudRetro issue. Feel free to reopen if new input becomes available.

Based on the information below, what is the culprit here? Is there anything I can tweak server side to facilitate this discovery and ensure a successful connection on first attempt?

error attempt

success attempt
