Getting "An unknown error occurred" while registering ENS domain

I am registering a domain dapplooker-node.eth on ENS, 1st transaction is done but for 2nd transaction, Open Wallet button is disabled and show below error:

Hey @hitesh-dapplooker could you create a support ticket? This way support mods can get a little more details on the error. You can open a ticket using the support chat feature on It will be easier and more private than trying troubleshooting steps on the public forums. Would definitely be useful to get more information so please start a support chat if you’re still having this issue.
