Mempool does not load BTC addresses

When I add in a Bitcoin address in my mempool and search for it

Then after a while I get this:

Error loading address data.
There are too many transactions on this address, more than your backend can handle. See more on setting up a stronger backend.

Consider viewing this address on the official Mempool website instead:
https://mempool.space/address/bc1xcvdsf

Anyone know why this happens?
My Bitcoin Knots node is 100% synchronized
