The address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v is invalid; the checksum test failed or it's an unconvertible IBAN address

I’m running into an issue with a Solana address: EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. When I try to use it, I receive the following error message:

"The capitalization checksum test failed, or it’s an indirect IBAN address which can’t be converted."

I’ve already double-checked for any typos and even validated the address on Sol scan. Everything seems correct, but the error persists. Has anyone encountered this issue before, or does anyone have suggestions on how to resolve it?

Thanks in advance for any guidance you can offer!
