Only recently I have been unable to join a meeting via a link and I get the message Access Denied Error Code 1020. Some of the links do not give the meeting/passcode, so I have been unable to join. Why has this suddenly started to happen? Any help appreciated.

We also started getting this error when creating OAuth token.

When calling endpoint

https://zoom.us/oauth/token?grant_type=account_credentials&account_id=id_here to generate oauth token. In response, we get:

error code: 1020

We are also getting this error when registering users for Zoom meetings:

POST /v2/meetings/{MeetingId}/registrants (returns HTTP 403; Forbidden)

It appears to return the raw text 'error code: 1020' instead of JSON.

Hi pluto2020,

Can you please confirm what infrastructure you are using ?

We are using AWS ECS (docker container), this issue only appears on AWS network outbound calls to zoom api endpoint.

When we released (for testing) on Azure cloud (app services), its working and no issue as such, everything works without any issue.

Is this only specific with AWS cloud to zoom cloud ?

Our app is deployed on azure and we are getting this error. It only started today. We suspect the something on Zoom’s end is blocking the requests.

I just started having this error code within the last few days when using my laptop to access Zoom across all browsers. Does anyone know if this is an issue with Zoom, my ISP, or something else? All other devices can connect just fine.

Interestingly, the issue only occurs for me in QA & PROD where we run our application in Docker containers (AWS ECS), but it works fine when I run directly from my development machine. The issue appear to start for us about 12 hours ago.

I’m a medical provider who is not well versed in IT terminology. I’m using a regular browser to access the Zoom website. Not sure what software may be causing the issue here unfortunately.

We're experiencing the same issue - we use AWS ECS to make outbound requests to Zoom.

We captured one of our outbound requests from our Staging environment and sent it locally via Postman and it works locally but NOT in our environments in AWS.

We found this article as well https://kinsta.com/knowledgebase/error-1020-access-denied
If Zoom is using Cloudflare, there could be a misconfigured firewall rule.

We also tried to rotate the AWS Nat Gateway IP but same issue.
