I am on the BTCarmory.com site. I clicked on the link for the signing keys (Armory signing key (4922589A).) and it comes up as a bad request? What am I doing wrong? When I try and add the my GPG verification tool it comes up as no keys found? What am I doing wrong?

When I use the other signing key on this forum Armory "Offline Signing Key": 0x98832223 the link comes back
