treenutz68 I can reproduce it when Play services have the network permission revoked during the Signal account setup. Any chance you could double-check that permission for Play services?
(Also, Signal complains about missing Play services when Play services are disabled as a whole, but I assume that your profile has it enabled).
treenutz68 play services version 24.44.33
gmscompatconfig version 150
Edit: I possess the same versions, but not sure it matters.
