Failure to contact a key server

Hi,
the unique log that I was receiving was this:

gpg: directory '/home/circleci/.gnupg' created
gpg: keybox '/home/circleci/.gnupg/pubring.kbx' created
gpg: keyserver receive failed: Cannot assign requested address
gpg: keyserver receive failed: No data
gpg: keyserver receive failed: Connection timed out
Exited with code 2
