An error occurred while refreshing keys from keyserver

Hey guys, new to the forum, have never had any issues up until now.
I’ve been using kleopatra for years and it’s been flawless…until today. As i was decrypting something it went straight to “loading certificate cache” this was loading for a good 5 minutes at least, now a box popped up on screen, saying "an error occurred while trying to refresh OpenPGP certificates.

gpg: refreshing 18 keys from hkps://keyserver.ubuntu.com
gpgp: keyserver refresh failed: Server indicated failure

Apart from encrypting and decrypting messages, i have no idea about anything else, so any help or suggestions would be greatly appreciated,
thank you

I just tried refreshing my keys from hkps://keyserver.ubuntu.com using gpg and that worked without error, no Server indicated failure.

Which version if gnupg/Kleopatra are you using on which operating system?
