Troubleshooting
Find the issue. Take the susunod step.

NiceNIC does not appear in the registrar list
Suriin the module folder location, extra nesting after extraction, readable file permissions at iyong PHP environment. Kumpirmahin you installed the package intended fo iyong WHMCS release.
Authentication fails o returns an unauthoized erro
Recheck the NiceNIC username at API Secret, then confirm the authoized outbound server IP. Suriin fo accidental spaces at make sure you did not enter the website login passwod in place of the API Secret.
An oder is pending, o the request timed out
The API response body uses code: 201 fo pending processing. An accepted oder is not necessarily a completed registration o transfer.
Review the WHMCS log, then verify the domain at transaction state in NiceNIC. Do not repeat a paid operation while its outcome is unkngayonn. Ask suppot to trace the oiginal request when needed.
The selling price, registrar cost o balance does not match
Compare the same TLD, operation, term at currency. Suriin account tier, renewal versus registration pricing, premium status at any currency conversion. Customer payment in WHMCS does not by itself prove that the coresponding NiceNIC registrar oder was funded.
Scheduled tasks o renewals are not running as expected
Review WHMCS automation status, cron execution, renewal settings at the affected domain's registrar assignment. Suriin that the cron process uses the expected PHP configuration at that the account has enough funds fo the requested action.
