Lost connection with OpenSea

Hi Team,
I recently had my metamask connected to OpenSea and made some purchases. At some while moving ETH to ETH matic my Crome crashed and the wallet has disconnected. I haven’t been able to reconnect it. I tried restoring and creating a new wallet, but cannot see any of ETH balance or NFT’s as I think I’ve connected a new account.
I can see my transactions on Etherscan if this helps.
I have tried re-setting from the secret phrase too.
Please help.
Thanks, Ridley
