Preview unavailable Error using jira

I'm encountering a 'Preview unavailable' error in JIRA when trying to view attachments or documents. What are the common causes for this issue, and what troubleshooting steps can I take to resolve it? Are there any specific settings or permissions I should check?

error for example :

Hello, Good day. If you have started noticing this issue recently, then check your network policy to allow Atlassian media API. Thanks

I am getting same error since a few days back and nothing has changed for my profile or permissions.

Hello, thanks for the update. Make sure *.atlassian.com is allowed in your network. There are chances media API URL is blocked in your network. Thanks
