Well, sure, but after I saw I couldn't connect I downloaded the current version of PGAdmin and psql and couldn't connect with them either. > More below. > >> When trying to connect from PGAdmin 4 the server logs say: >> 2019-02-05 10:34:30.558 CET [31051] [unbekannt]@[unbekannt] LOG: 00000: Verbindung empfangen: Host=ip5b4054ce.dynamic.kabel-deutschland.de Port=50262 >> 2019-02-05 10:34:30.558 CET [31051] [unbekannt]@[unbekannt] ORT: BackendInitialize, postmaster.c:4249 >> 2019-02-05 10:34:30.648 CET [31051] [unbekannt]@[unbekannt] LOG: 08006: konnte Daten vom Client nicht empfangen: Connection reset by peer >> 2019-02-05 10:34:30.648 CET [31051] [unbekannt]@[unbekannt] ORT: pq_recvbuf, pqcomm.c:978 >> ("konnte Daten vom Client nicht empfangen" means "couldn't receive data from client") >> PGAdmin says the usual " Unable to connect to server:..." >> No issue connecting from the Mac. >> I see in the logfile that other windows users did connect successfully from their windows boxes so I am ready to believe that maybe my Parallels somehow disconnects the connection quickly or something. >> Another strange thing is that if I try to connect from my Xojo app (which uses libpq internally) it says:SSL error: unknown protocol.

Yes. Also the errormessage wouldn't be "Connection reset by peer" if it was a pga_hba.conf issue, would it? And anyway, I can connect just fine from my Mac with the same credentials. I wonder if this is maybe some Parallels issue. Thanks, Max
