I have created a zoom app on marketplace and copied the credentials into the .env file inside the cloned repository. I am using ngrok to access the app from the internet. I am using Ubuntu 20.04. While opening the zoom client app, I am greeted with the Error code 122 inside the popup window from the Zoom Client. ![Screenshot from 2023-07-17 18-37-18](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/7/e/7e83b30ffbbf8e706989655017b8149735394388.png) So far, I have tried using in Incognito windows and relogging into my client window, but to no avail ---

Error code 122 typically indicates a problem with the app’s authentication or setup. Here are steps to resolve this: 1. **Check Credentials** : Ensure the credentials in your `.env` file are correct and match the ones on your Zoom Marketplace app. 2. **Verify Ngrok Setup** : Ensure your Ngrok tunnel is correctly set up and the URL is correctly configured in the Zoom Marketplace app. 3. **HTTPS Requirement** : Make sure your Ngrok URL uses HTTPS, as Zoom requires secure URLs. 4. **OAuth Redirect URL** : Confirm that the OAuth redirect URL in the Zoom Marketplace settings matches your Ngrok URL. 5. **Clear Cache** : Clear your browser cache or try accessing in an incognito window again. 6. **Restart Services** : Restart your local server and Ngrok to ensure all services are running correctly. If the issue persists, consider checking Zoom’s developer forum for more specific guidance or contacting Zoom support. ---
