Fail with error 'no more slots'

Hello.

All seems to be ok, however when I go through the process on becoming a official validator using:

I get through the process successfully… and then it fails on funding the account. When I try and add Polygon to stake it fails with the following error on Etherscan when I try to send funds using MetaMask:

Hey thanks for letting me know. I wish this was in the docs or somewhere in the process. I spent many hours and $ in fees creating a new validator server.

Thanks
