I have mistaken 8l with 81.
So, you were entering the address manually.
If you are going to do the same thing instead of copy-pasting the address in the future for any reason, take note that to avoid confusion, some characters are always excluded.
Addresses that start with 1 or 3 can't contain 0 (zero), capital letter O, capital letter I and lowercase letter l.
Addresses that start with bc1 can't contain 1, B, I, O in their next characters.
Take note that native segwit addresses (those that that start with bc1) aren't case sensitive. So, both b and B, both i and I and both o and O are excluded in them.
