Hey ​@Preetika Kardam, thanks for flagging this! 

 
Can you please try the following and let me know if this helps?
 

• Can you confirm that your network is set up correctly to run Figma? More details about the domain that needs to be allowed can be found here: Adjust your network settings
• Can you try connecting via a different network such as a mobile hotspot, and then check if you can publish?
• If using any VPN or proxy can you try disabling these and try publishing again?

 
If the above has not helped, can you please send the following:

• A screenshot of what it says when you click 'View settings' in the error in the screenshot you sent?
• Does the issue happen in all files, and with all components or just some?
• Can you please run the network check detailed in this article and send a screenshot of the results to me? 

Here are the steps:

Thank you for your help!
