Which ports are required for WHMCS to work?


Recommended Posts



Ive tweaked a few settings on my VPS and WHMCS seems to have stopped working properly. And i cant trace the issue back,


Im sure its a firewall problem, and when i check for updates i get the following error:


Update Check

Connection Failed - Check your servers firewall settings…


Also when i do a licence info check i get:


Registered To

License Key Leased-dc60d932f39dc8b**** (blanked for security)

License Type

Valid Domain

Valid IP




Apart from the licence details everything else is blank.


Domains don't get auto registered either.


Here are the ports i have open:


IN: 20,21,22,25,53,80,110,143,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,8443,20001,30000:50000,8000,10060


OUT: 0,22,25,37,43,53,80,110,113,443,587,873,2086,2087,2089,2703,8000,8443,10060,20001


Any help would be great
