Re: Cannot create PoolableConnectionFactory (The connection attempt failed.)

Ok,

Try add following for your Tomact's Java (I haven't worked for years with
Tomcat but there may be run.bat, run.sh, it will be probaly somewhere near "-
mx"):
-Djava.net.preferIPv4Stack=true

and/or (on Linux)
echo 0 > /proc/sys/net/ipv6/bindv6only

and/or
expose PostgreSQL on IPv6, and change hostname to ::1

Regards,
Radek
