Hello, we are using the Google Chrome MetaMask extension wallet. How do we set up a whitelist in a restricted network (Fortinet firewall)? We are currently unable to log in to the wallet, even though the RPC address has been added to the whitelist.
Hi, I think you would need to check with the firewall provider regarding that.
Always be careful who and what you interact with online and always do your own research before doing anything! 
Got it, thank you for clarifying. I’ll check with the team regarding this and we will let you know here as soon as we have an update!
Chatting with the team, and they’re thinking its one of the settings related to NFTs.
You’ll likely need to reset the wallet to drop the RPC requests that are failing.
Before re-adding the RPC on a clean install, from the 3 lines menu > settings > Security and Privacy: Turn off “Display NFT media”, & “Autodetect NFTs.”
If the problem goes away there we know that’s the cause, and can work towards a permanent solution. (if not, we’ll need to work through the other toggles related to security/external connections to determine which one is causing it)
