Connectivity Issues

If you need assistance finding the reason out why your login fails, please reach out. We can look this up in ease and provide help. Still, find below a whole chapter for reference guiding you through the issue.

Upgrade your Module

To ensure you’re not affected by a bug that got recently patched, please upgrade the registrar module. Find the upgrade steps documented in the Registrar Module Guide.

Working Ping

Ensure a ping is going through - otherwise, there’s a network or setup error (firewall etc.). Please execute this via command line on your WHMCS Server:



We in general communicate base on HTTPS protocol - port 443 though. Ensure that such communication is allowed in your firewall.

Required Dependencies

Ensure to have the Requirements of our Module fulfilled:

  • curl,
  • php-curl

… have to be installed and working.


You can test curl with the following shell command:

# test with your OT&E credentials (OT&E System)
curl -k -d 's_login=<your username>&s_pw=<your password>&command=statusaccount'

# test with your LIVE credentials (LIVE System)
curl -k -d 's_login=<your username>&s_pw=<your password>&command=statusaccount'

You should get something like:

code = 200
description = Command completed successfully
runtime = 0.003
queuetime = 0
property[amount][0] = 37071.82
property[credit][0] = 0.00
property[credit threshold][0] = 0.00
property[currency][0] = GBP
property[registrar][0] = <your username>


Find a test script here. Download and execute it via command line:

# Test Connectivity with OTE System
php test.curl.php OTE "<your username>" "<your password>"
# e.g.
# php test.curl.php OTE "testuser" "gre§$Tgagr"

# Test Connectivity with LIVE System
php test.curl.php LIVE "<your username>" "<your password>"
# e.g.
# php test.curl.php LIVE "testuser" "gre§$Tgagr"

If this works, you should see a similar response as shown in the previous point.

Other Reasons

  • check if TestMode is turned on in the registrar module settings and if this is desired. If so, you’re connecting to the OT&E system, otherwise to the Live System. Ensure to enter your credentials also in the right fields as we offer totally separated password fields for the LIVE System and OT&E System.

  • You configured IP Whitelist is not including the ip address(es) of your WHMCS Server. This only applies in case such an IP Whitelisting is in place.
