Can’t connect ETH Account to Flexa Capacity


I’m trying to connect my MetaMask wallet to Flexa Capacity in order to stake AMP token. When I connect my wallet, it shows my AMP balance available, but not my ETH (I need ETH to pay the gas fees), but I definitely have ETH in my account. I get the error message “there was a problem connecting your ETH account”. Why is it that my wallet connects for the AMP balance but not the ETH?
