I have a problem when I tried to remote PostgreSQL Server (in Linux Centos) from my PgAdmin Client (in Windows), there’s an error message displayed on screen said “could not connect to server: connection timed out (0x0000274c/10060) is the server running on host and accepting tcp/ip connections on port 5432?”
I checked my firewall status with :
systemctl status firewalld
It said that my firewall status was Active: failed. From here I’m sure there’s problem with my firewall process, because if the firewall stopped successfully, the status will be inactive like this image below :
After tried many solution, I ended-up with this one :
systemctl unmask firewalld
Next step after run unmask syntax, I tried to restart my firewall and it runs flawlessly :). Hope this thread help you guys.
