Other valuable info

I"ve edited my log to show "MYWEBSITE", actually it shows the proper URL.

[szaimen]

Hi, is talk working in general and only the recording doesnt?

[y4my4my4m]

@szaimen yes that's correct, Talk is working as expected. Only Talk Recording has issues starting.
It'll attempt to start recording, then say "recording couldn't start contact your administrator" and the logs will throw what I've posted above.

I've verified in the Nextcloud Admin > Talk area that the secrets and URls are fine ✅. Attempting to disable SSL verify didn't change anything.

[szaimen]

Can you also post the talk container logs from when this happens?

[y4my4my4m]

@szaimen
There are no logs displayed from nextcloud-aio-talk when the recording is requested or when it fails to start. The only logs I can retrieve are from nextcloud-aio-talk-recording.

However just in case, here are the talk container's logs from the moment the call begins:

Hm...

[szaimen]

This looks like the underlying issue:

WebDriver session does not exist, or is not active

[szaimen]

I found this thread: https://stackoverflow.com/questions/56483403/selenium-common-exceptions-webdriverexception-message-invalid-session-id-using

[szaimen]

How much ram and how many vcpus does your server has btw?

[y4my4my4m]

@szaimen

I found this thread: https://stackoverflow.com/questions/56483403/selenium-common-exceptions-webdriverexception-message-invalid-session-id-using

I did the auto install from AIO dashboard. However I am using an nginx reverse proxy (from the Readme).
Are there specific requirements that I need to add to the reverse proxy for talk-recording?

How much ram and how many vcpus does your server has btw?

As per Nextcloud's system info:

CPU: Intel(R) Xeon(R) CPU D-1521 @ 2.40GHz (4 cores)
Memory: 4.84 GB

Not sure why it shows 4GB because I actually have 6GB but i suppose docker and the OS itself is eating a bunch of it?
4 vCPUs

[szaimen]

Thanks! Which optional addons do you have enabled in the aio interface?

[y4my4my4m]

@szaimen

I barely have anything on it by the way, this is a fresh install.

[szaimen]

Hm... that should usually work fine. Can you monitor the ressource usage of the server when you are attempting to record a call? Can you for that e.g. use htop on the server and post a screenshot when attempting to start the recording?

Also can you please post the output of the following command here after the recording fails to start?
sudo docker exec nextcloud-aio-talk-recording cat geckodriver.log

[szaimen]

Moving to discussions as I cannot reproduce this and without the above information it is not possible to further debug this.

@szaimen sorry for the delay,

I've added even more RAM and monitored it during operation, it doesnt seem to go over... (2gb of ram used out of 6gb, CPU peaking at 1%)

Here is the gecko log:

@Zoey2936 sorry for pinging you directly but do you have any idea what could be wrong with the above config?

[Zoey2936]

looks good

is the problem then...

[y4my4my4m]

@szaimen Docker version 24.0.2, build cb74dfc
I'm running it directly as per the guide btw, no docker-compose.

[szaimen]

All right. Can you try to do the following and report back if it makes it work?

sudo docker stop nextcloud-aio-talk-recording
sudo docker rm nextcloud-aio-talk-recording
sudo docker image rm nextcloud/aio-talk-recording:latest

and then stop and start all containers again

[y4my4my4m]

@szaimen unfortunately this doesn't solve it either

something strange has happened after doing it though (i've also attempted to do it for the talk container afterwards)

Now, when the High-performance backend is added, i cannot start a video chat anymore
only when i remove https://MYWEBSITE.com/standalone-signaling/ does it work (but obviously doing so i cannot use the recording feature anymore).

The backend server used to work though, i've tried it and tried to start recordings when 2-3 users were in the video call!...

From the talk container logs:

is there a way to completely reset both talk and talk-recording, volumes and data as well?
(get new secrets, redo the .conf files from scratch, etc)

[szaimen]

Something seems to be very wrong on your instance. I cannot reproduce any of it unfortunately.

[y4my4my4m]

@szaimen
I found this:
https://help.nextcloud.com/t/how-to-setup-nextcloud-talk-recording-backend/159145/49?page=3
I tried running the suggested docker standalone version but can't seem to get it to connect...

[szaimen]

Lets keep trying with the built in one. Please answer my question above

[y4my4my4m]

Also, maybe related to this other issue?
#2676

[szaimen]

I dont think so

Is there a solution for this problem, I am running nextcloud aio on an oracle cloud free tier machine with 24gb ram and 4 cores, at first I just did the installation everything was working correctly, then one day it stopped working, I spent a day to reinstall everything nextcloud aio from scratch but the recording did not work again, the same error is generated. Can you help me please?

[egelhaus]

Same issue here

[vitalymp]

Unfortunately, Talk Recording does not work for me. When I try to start a recording, I get an error message telling me to contact the admin. However, the connection to the backend seems to work. Unfortunately I could not find the Gecko.log.

Aio is running behind a Caddy Reverse Proxy in a user defined bridge network. Can someone help?

Still same issue!

[manuelkamp]

I think i have the same issue as OP. Herer are my docker logs.
Running on the same LXC where my nextcloud runs. CPUs available 24. RAM available 16 GB. HPB runs on a different server. Talk with signaling and everything else is working fine, only the recording part does not work.
Not using NC-AIO (using bare metal installation), but HPB-AIO on different server.

also tried a recent build instead of latest:

every time resulting in the same error.

the LXC os is Ubuntu 22.04

Hi there, i have the same or very similar problem with my nextcloud-aio installation. Any Idea what this triggers?

• Netcup Root Server 8 Cores, 16 GB RAM
• Caddy Reverse Proxy with user defined docker network
• Every other App works in Nextcloud like Collabora etc.
• Talk works and Talk Video Calls are fine
• It s only Recoding that gives an Error Message: Contact your Admin

Every help is much appreciated.

[iamdoubz]

I don't know how, but I was able to fudge around and figure out how to get recording to work!

My setup

Server 1

• Ubuntu 22.04
• nginx 1.29.4
• Nextcloud Server 32.0.5 (on prem AKA no docker)
• PHP 8.3 FPM

Server 2

• Docker 29.1.4
• Server 2 runs a docker-compose with high performance and recording backend all in one file

High view

Outside world <---> Router <---> Server 1 <---> Server 2

Nextcloud URL: nextcloud.my.domain
HPB URL: hpb.my.domain/standalone-signaling/
Record URL: hpb.my.domain/
TALK_HOST: This should be the same as the TURN server that you configured on the Admin, Talk, TURN servers section i.e. turn.my.domain

TURN_SECRET, SIGNALING_SECRET, INTERNAL_SECRET have been generated with openssl rand -hex 24.

SIGNALING_SECRET and INTERNAL_SECRET are the exact same values between the two containers.

Docker compose

services:
  nextcloud-hpb:
    image: ghcr.io/nextcloud-releases/aio-talk:latest
    container_name: nextcloud-hpb
    mem_limit: 1G
    restart: always

      - TALK_HOST=turn.my.domain
      - TALK_PORT=3478

      - TALK_MAX_SCREEN_BITRATE=7500000 # 7.5mbps

      - SIGNALING_SECRET=`openssl rand -hex 24`

      - SIGNALING_SECRET=`openssl rand -hex 24`
    #shm_size: 2147483648
    restart: always

Reverse proxy

Again I use nginx. I did nothing to my base nextcloud config file. I added a new file called hpb.conf into where my nginx configs are i.e. /etc/nginx/conf.d. Relevant config shown below. NOTE: server2 is the IP address of my second server that hosted the docker containers for HPB and Talk Recording.

upstream signaling {
    server server2:8081;
}
upstream recording {
    server server2:1234;
}
server {
...
### Proxy rules ###
  location /standalone-signaling/ {
    proxy_pass http://signaling/;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
  location /standalone-signaling/spreed {
    proxy_pass http://signaling/spreed;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
  location / {
    proxy_pass http://recording/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }

}

Results

Ultimately, you get a recording saved to the user who started the recording in the Files app root called "Talk" followed by "Recording" then a random call key. It produces a .webm file. My recording was 1:27.7 seconds long, ~11.3MB; video is vp8, yuv420p, 1920x1080, 29.97 fps, bitrate 1087kb/s; audio is opus 48000 Hz stereo.

Final words

Hope this helps someone!
