Nextcloud Server version: Nextcloud Hub 25 Autumn (32.0.6)

PHP version: 8.3.25

Hi everyone! I’m testing adding a HPB server to Talk and am having the following problem (Unknown error):

But if I check from the Nextcloud server via curl, I can see that HPB is configured correctly:

# curl https://my.signaling.domain/api/v1/welcome
{"nextcloud-spreed-signaling":"Welcome","version":"unknown"}

# curl -i https://my.signaling.domain/api/v1/welcome
HTTP/1.1 200 OK
Server: nginx/1.24.0 (Ubuntu)

{"nextcloud-spreed-signaling":"Welcome","version":"unknown"}

Could you tell me what logs I should look at on the NextCloud server to figure out the problem?

Thanks!

Okay! That was my problem and I shot myself in the foot. I was able to fix it:

I tried to find the tokens in the database and delete them, but it didn’t work:

SELECT * FROM oc_appconfig WHERE configkey LIKE 'signaling_token_%';

DELETE FROM oc_appconfig WHERE configkey LIKE 'signaling_token_%';

Then, by pressing F12, I saw the following line with error 403:

https://my.signaling.domain/ocs/v2.php/apps/spreed/api/v1/bot/admin

When I opened the link in the browser, I encountered an access denied error.
I realized I’d allowed several groups to use Talk that weren’t part of the administrator account I used to configure it.

This also caused an issue with the mobile client, with an HTTP 426 Update Required error, but I’m still investigating that.
