In this article, we’ll be looking at the WHMCS “error in your request” error.
Power your own hosting business with InMotion Hosting reseller packages.
Reasons for the “There was an error in your request” Error
In most cases, this error results from port blocking. If searching for domain availability in WHMCS, you may see this error if your host is blocking port 43. You may request that your host open this port; but, in shared hosting, it is unlikely they will assist in port openings or closures (for security purposes).
Port Blocking
For more information about which ports are open or blocked for security reasons in your reseller hosting account, please contact live support anytime.
