Обсуждение: PgAdmin cannot locate my server
I’ve got something really weird going on. My laptop can easily find my PLE production (production like environment) usinga 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 onit should be able to do so. — Jay Sent from my iPad6

I can't find message "Unknown host" in the pgAdmin source. I'd have to check but I assume pgAdmin delegates all connection management to psycopg. > I would think that if the laptop can find it, that any app running on it > should be able to do so. How do you run pgAdmin? From the top of my head there's the desktop version, server version, and Docker container version. In case of the server version it's plausible that the server uses different DNS settings than your laptop. Docker containers should inherit the DNS settings of the host but that can be changed as well. -- Erik
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 dottedquad. 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@gmail.com> Sent: Monday, April 17, 2023 12:45 PM To: Pgsql-admin <pgsql-admin@lists.postgresql.org> Subject: [EXTERNAL] PgAdmin cannot locate my server I’ve got something really weird going on.

You are correct this problem was from windows and PgAdmin 4v6. At least that’s what my company calls it. The database wasan AWS RDS version 12.4. The eventual fix was even stranger. As an experiment I ran nslookup against the db. Then I reconfigured PgAdmin to connectusing the db’s IP address. That all went quite well and I connected with the db. For grins, I reconfigured PgAdminback to the db’s FQDN, and had it try a reconnection. Strangely enough it did connect and there were no issues., butthe only change here was the fact that I first connected using the IP adress.
