Welcome to the MetaMask Community @Ke20!! 
Do NOT! “validate” your wallet at that site. That is a scam and they will completely clear out your wallet. NEVER give your seed phrase to anyone for any reason.
We do NOT provide support on Telegram or via DM on Twitter. You can find a list of our official support platforms here.
Are you trying to send your USDT to or from your MetaMask wallet? What error are you receiving? Can you provide a screenshot?
