Registration has not been enabled happening before meeting and dissappears at some point

Hey @raresmldvn31,

Thank you for reaching out to the Zoom Developer Forum. This seems to be related to a known issue which our engineering team is investigating as a priority.

Workaround

In instances where you receive a 404/"registration not enabled for meeting *****." error, you can make a subsequent PATCH request to the Update Meeting API with the original meeting settings for the Meeting ID returned in the error. On successful update, you can then re-attempt the registrant request after you’ve made this Update request. For example:

If you receive an error such as 404/"Registration has not been enabled for this meeting: *******." you can have this trigger a request such as:

PATCH https://api.zoom.us/v2/meetings/{{Meeting ID}}
{
  "settings":{
    "approval_type": 0,
    "registration_type": 2
  }
}

I’ll be sure to update you here as the issue progresses. Let me know if you have any questions.

Thanks,
Max
