Remote API from WHMCS - 415 Unsupported Media Type Error

Issue

As of today our remote WHMCS is unable to communicate with our cPanel servers.

If a user tries to one click login to cPanel OR we try to do a password reset/package reset from WHMCS we will get this error in WHMCS

cPanel API Unreachable: <html> <head><title>415 Unsupported Media Type</title></head> <body> <center><h1>415 Unsupported Media Type</h1></center> <hr><center>openresty/1.27.1.1</center> </body> </html>
the fix is to login to each WHM > Imunify360 > firewall and whitelist the WHMCS Server IP

This only started today and effecting all of our cPanel servers.

the workaround fixed the issue but i wanted to bring this to your attention.

Environment

  • cPanel
  • Imunify360

Solution

This can be resolved by adding the WHMCS server IP address to the Imunify360 white list. Use the below command.

imunify360-agent ip-list local add --purpose white 11.22.33.44 --comment "one good IP"

Replace 11.22.33.44 with actual IP address.
