I've recently inherited a portal configuration (version 10.6). The apps seemed to be running fine yesterday; however, now they are down and I am unable to access the portal homepage.
I've attached the .log files under <install dir>\framework\runtime\tomcat\logs folder - as far as i can gather the problem seems to be outlined here:
'Cannot connect to database: jdbc:postgresql://localhost:7654/gwdb Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.'
Any help would be appreciated. I'm a long time ESRI user, first time portal admin!
