I'm assuming this is windows. I ran into this when PGAdmin is fine with qualified DNS hostname, but the pg_pass file couldn't resolve and needed dotted quad. The corporate-world structure of windows networking and permissions is a mystery to me... Just use the dotted quad and move along! lol >From cmd: nslookup < ple.mydomain.com > pg_pass.conf <IP.IP.IP.IP>:<port>:<db>:<User>:<PASSWORD> -----Original Message----- From: John Scalia <jayknowsunix@xxxxxxxxx> Sent: Monday, April 17, 2023 12:45 PM To: Pgsql-admin <pgsql-admin@xxxxxxxxxxxxxxxxxxxx> Subject: [EXTERNAL] PgAdmin cannot locate my server I’ve got something really weird going on. My laptop can easily find my PLE production (production like environment) using a normal nslookup, but PgAdmin emits an error saying could not translate host name “ple.mydomain.com” host to address: Unknown host So where is PgAdmin looking regarding DNS entries? I would think that if the laptop can find it, that any app running on it should be able to do so. — Jay Sent from my iPad6
