Gas fee network error coinbase to metamask

Hi there,

I really need help as two of my metamask wallets give me the same error and have had the same issues. Firstly, when I try and send 0.00 ETH to my account to I get the message “Gas price estimation failed due to network error.” and I cant fix it? It doesnt let me send the money and seems stuck on the page as it cant estimate the gas fees for some error. I cant recieve ETH properly either as its stuck in “recieve” in the activity area. Any help would be much appreciate!!

Thank you.
