METAMASK not working with etherscan.io

Hello, since few weeks i am trying to validate my account on OpenSea but the transaction stay in the loop for several days and then nothing happen… If i would like to check the status with etherscan, no transaction are linked to what I can see as a pending transaction in my wallet from the extension… what could i do? I tried different browser also, Brave, Chrome, Sidekick… I cannot validate any transaction!!
