Nextcloud talk API randomly returns 404

Thank you for your reply

I’m trying to set up a script that would trigger a call, I don’t get what I should do then

My script actually :
Perform the curl call with flags:1
Sleep 10 seconds
Perform the delete call to leave the call

I am missing something ? I don’t get what I need to do with the signaling API. I tried to reproduce the calls a browser is doing
