Can't claim BCC from BTC.com

[PrimediceRegistry]

Whenever I try to claim my BCC (I've had over 30BTC received before the 2017 BCH fork) it gives me this error:
"Import Error
Input is not a valid or supported backup phrase/mnemonic."

What should I do?

It seems your wallet is not fully unlocked as the mesaage says failure in backup of phrase/mnemonic seed.
If is better if you can provide the screenshots of what you are getting and from which window or try to logout and relogin to see if this attempt could resolve your issue

Here's a screenshot of me trying to claim the BCH with my blockchain.info private key (of the address that I had 30+BTC total received before the fork -- not sure if I had any BTC on exactly Aug 1, is that the problem?): https://prnt.sc/k2wwpo

Better move this topic to the technical discussion because it is related to the bitcoin so where you can get the answer what you are looking for.I am not familiar with the forks and importing the forked coins so let an expert answer you soon.
