Hi,
When i try to check for domains in whmcs i get the below error.
"There was an error in your request"
I found whmcs Documentation saying, Need to UnBlock port "43" if using any firewall. I have done it as suggested and restarted the firewall (using CSF), But failed to resolve the issue.
The same errors in another 3 more (WHMCS) sites hosted on this server,
Server specs (cloud linux, CSF, cpanel)
Please suggest me if any thing that i have missed out to make domain check work.
Thank you in advance.
