Custom Domain - Upload, Download, & Preview Errors

Custom Domain - Upload, Download, & Preview Errors

While using the Custom Domain feature in ZohoLearn, you may experience an instance where user actions like upload, download, or preview may not work, with other functions working properly.

Since domains are different for Custom domain enabled orgs, the actions mentioned above will not work if third-party cookies are blocked. There are no other alternatives, and it is not a bug on our end. It is a known limitation and browser behavior. You will face this issue for services that support custom domain and using different domains within the product.

To solve this problem, we suggest you follow the below steps:


Step 1: Provide access to your custom domain using your Zoho Account

When the team members log in to their Zoho Learn account for the first time via the newly configured custom URL, this page will appear.



Click the Trust this website checkbox, then click GRANT ACCESS to access the ZohoLearn account through the custom domain. This one-time action will help you experience smooth and consistent ZohoLearn account usage in further sessions.

Step 2: Enable third-party cookies to your custom domain

Add this custom domain URL to the 'Always use Cookies' section of your browser cookies settings to experience seamless ZohoLearn usage.

FAQ

1. Why is it necessary to enable third-party cookies?

Say you are accessing a domain named learn.zylker.com, and within this page, another API call is triggered with the domain upload.zoho.com to upload a file. The browser will treat upload.zoho.com as a third-party domain, as it does not belong to *.zylker.com.

2. What is the purpose of upload.zoho.com in Zoho Learn?

For a faster and enhanced upload experience, we are using different domains based on the requirement. For upload, we are using upload.zoho.com.

3. How do custom domains work?

When you access the custom domain learn.zylker.com, we will add the necessary details in the cookies in both learn.zylker.com & *.zoho.com domain.

All major browsers block third-party cookies by default in their latest versions. Once it is enabled, cookies will not be added when we access upload.zoho.com within learn.zylker.com. Our server will throw an unauthorized error, because user cookies were not added in the request.

5. Why is the issue only reproduced in the custom domain?

Without a custom domain, the ZohoLearn product will load in learn.zoho.com, and upload requests will be triggered in upload.zoho.com. Both domains belong to *.zoho.com. Browser settings will not block cookies. That's why upload is working in learn.zoho.com
