Zoom LTI Pro Moodle Error 2216

[SampsaCSC]

On Monday 29th September 2025, at least five institutions in Finland, as well as some institutions in Norway and Iceland have faced "Warning. The instructors email is invalid(2216). Error Code 2216 - int_edu_{institution specific numbers}" when trying to access Zoom via Moodle LMS as the Moodle instructor role user. This prevents instructors, typically university teachers using Zoom the way they are used to. In addition to this, institution admins are facing "Sorry, your session was expired. Please refresh the page or login again." when trying to configure LTI Pro settings, which are unexpectedly empty.

No problems on Friday 26th September 2025. The issue started on Monday or during the weekend.

Norway and Iceland reports mention this error occurring also in Canvas LMS integrations.

However, there are institutions who use Zoom LTI Pro and Moodle LMS who are not affected by this issue.

We have checked that Moodle site > Site administration > Plugins > Activity modules > External tool > Manage tools > Zoom LTI Pro tool > Edit > Privacy setting > "Share launcher's email with tool" is enabled.

We contacted the Zoom Support and based on their advise we have checked or tried the following:

1. The instructor's email is not yet created in Zoom as a member of your account.
2. The email address used in Moodle is different from what's signed up in Zoom.
3. The access token does not have the sufficient API scopes.
4. Can the Owner or an admin of the account re-authorize LTI Pro in the Zoom App Marketplace again?
5. After checking these, Zoom deemed it necessary to remove-then-reinstall the LTI Pro app in the Zoom account to resolve the issue.

Institutions are now looking into possible problems that may be caused when reinstalling LTI Pro, such as links no longer working in Moodle after the operation, before reinstallation. Has anyone else had this issue outside the Nordics? Does anyone know how to fix this?

UPDATE: The issue was solved on the 1st of October, 2025. The resolution can be found in the comments.

We are located in Norway and are also seeing this issue. We are using Canvas with LTI Pro. Would be grateful for any information if someone figures out what the issue is.

[SampsaCSC · Accepted solution]

We found the solution for the Finnish community on the 1st of October. Go to LTI Pro settings, under "Manage app" click the red button "Remove" (found under "Remove App - Once removed, the app will be deactivated for you."). Then add the LTI Pro app back to your Zoom account.

We hesitated to do this for a long time because we thought this would break Moodle courses, until Zoom support (and one university who had this problem a few years ago) encouraged us to do it. Fortunately the course data in Moodle remained untouched.

Hi SampsaCSC, thank you for this update! Can you please elaborate: after you removed and re-added the LTI App, did you ahve to configure and set it up again? For example, add all the Keys and their settings again? Does this resolve the problem of the "vanished" LTI Pro-Settings?

[torebr]

We followed your advice and removed the app and added it again, and then the integration started working again for the instructors. We didn't have to set anything up again from scratch, keys and settings were remembered. Thanks for the help 🙂

[stefanbaumgartn]

Yes can confirm! It works again 🙂

Can confirm same problem here in Austria. Canvas/LTI Pro 1.3. LTI App Settings are unexpectedly empty. Zoom Support was contacted and is investigating.

Same problem here in Austria. LTI Pro Settings are gone unexpectedly, no Zoom scheduling possible inside Canvas, same error message.

Question regarding: "After checking these, Zoom deemed it necessary to remove-then-reinstall the LTI Pro app in the Zoom account to resolve the issue." -> did you have to set everything up from scratch (keys, settings), or have they re-appeared after reinstalling the App?
