Cannot fetch GPG public keys with Kleopatra in Windows

In Kleopatra (Windows), I have the following key server Kleopatra Key Server

When I try to fetch the GPG public key of XUbuntu (843938DF228D22F7B3742BC0D94AA3F0EFE21092) using Lookup on Server functionality, Kleopatra doesn’t return anything

I’ve tried the following servers but nothing changed

  1. hkps://keys.gnupg.net
  2. keys.gnupg.net
  3. http://gpg-keyserver.de

I can fetch key successfully from CLI
gpg --keyserver keyserver.ubuntu.com --recv 6DAA6E64A76D2840571B4902528897B826403ADA
gpg: key 528897B826403ADA: public key “Werner Koch (dist signing 2020)” imported
gpg: Total number processed: 1
gpg: imported: 1

My Gpg4Win version is 3.1.16

My GnuPG version is like the following

gpg (GnuPG) 2.3.3
libgcrypt 1.9.4

I resolved the problem. At the time I had this problem, I was still using the old GnuPG version (the one before ver. 2.2.32). This messed up my debugging progress

Hi Kenzo,
good to know that you have solved your problem by upgrading.

Note if you need more keyservers to try, see https://social.tchncs.de/@ber/107008659842900171
