Posted: 2 years agoAsif Hasan PEGA replied to TharineNHi, Thanks for posting on PSC. It seems to be a generic issue with postgres instead Pega. You have to edit postgresql.conf file and change line with 'listen_addresses'. This file you can find in the /etc/postgresql/9.3/main directory. Refer:- Can't connect to postgresql port 5432 - https://github.com/PostgresApp/PostgresApp/issues/37 Hope it helps, additionally I'll try to find any Pega related bug which might be causing it and update here. Regards. Asif Posted: 2 years agoTharineN AI4Process replied to Asif HasanHi Asif, Thanks for the response. My observation : The Issue is getting fixed when, starting the tom cat server after restarting the whole system. (shutdown tomcat server -> restart the system -> start the tomcat server) Could not fix the issue as mentioned above, in the system where I didn't have the admin rights!!
