Subject: Fwd: pgadmin says "SSL error: tlsv1 alert no application protocol"

I was using PGAdmin with PostgreSQL 17 via Traefik 3 successfully since 
many months, but since I recently moved on to PostgresSQL 17 the UI of 
PGAdmin always tells me "SSL error: tlsv1 alert no application 
protocol". All other applications connect successfully.

I do not want to use TLSv1, and neither PostgreSQL 17 nor Traefik 3 is 
explicitly configured to use TLS v1. In PGAdmin I explicitly have set 
the min and max SSL versions to 1.3.

So I do wonder who in this game is using TLSv1 and how to get rid of it?

Thanks!

-Markus
