??? Please note that I am a developer of the upstream. The patch you addressed is already included in 2.1.18. My point is that currently there is a little issue in keyservers side themselves. One of keyservers in hkps.pool.sks-keyservers.net doesn't have valid combination of PTR record and A record. Current implementation of dirmngr is not robost enough to handle this glitch ... which should be fixed, IMO. --
