"gpg: no valid OpenPGP data found" error when importing public key from sks

Good afternoon, I have an sks server installed, which synchronizes with kleopatra, I create a pair of openPGPG keys, which I then publish to the sks server and it does it successfully, but when I execute the search option, it throws me the following error, as shown in the image

gpg: no valid OpenPGP data found
gpg: Total amount processed: 0
I have installed Gpg4win 4.1.0 and a sks 1.1.6 server

Hi,
right now I’m not sure if the SKS server and GNU still allow the search function and cannot check. To give you a first hint:

Try gnupg on the command line and add verbosity and diagnostic messages to it (and dirgmngr) to find out, what is going on.

–recv-keys is usually the option I use for a pubkey I know. Does it work with your server?

(BTW: many people use hockeypuck these days.)
