Figma Plugins not loading on work device with proxy

Hello,

Our company has mandated that all work devices connect to the internet via a .PAC proxy file. Our teams use Figma MacOS apps and are finding that images and functionality within plugins are not loading.

For example, the “Icons 8” plugin does not load with any images and the “Mockup” plugin is stuck on a loading state.

Could I please have some guidance on how to resolve this? Our IT team have asked us to request the URLs that plugins use so they can be whitelisted, however I feel this could be any number of URLs as plugins are made by third party developers.

Thanks,
Declan
