I accidentally unlinked Brave Rewards and now I cannot link it back

I accidentally unlinked my Brave Rewards to my Uphold Account, I know it sounds dumb but when I tried to relink it again I got this error on my Brave Rewards. Even changed my proxy to US still do the same.

Tried to reach out on Uphold and they said.

Sorry if I’m dumb to do that. Now I know that you shouldn’t do it.

Anyone could help me? Thank you! xoxo
