License check: error code: 1015

[Eduardo G.]

Hi! I'm having problems with license checking.

It looks like Cloudflare is rate limiting my requests to license servers, that's crazy!

Any similar experience ?

Testing Connection to 'https://a.licensing.whmcs.com/1.0/test'...
URL resolves to 172.67.4.33 ...
Response Code: 429
Connection Failed!

Raw Output:

Testing Connection to 'https://b.licensing.whmcs.com/1.0/test'...

It happens to me right now

WHMCS said it's because the SERVER_NAME changes

however there is no changes to the server configuration since last year

I am having same issue. My whmcs domain doesn't use cloudflare

I’m having the exact same issue with error 1015/429. Were you able to find a solution or figure out what was causing the problem?

Thanks in advance!

Support team just said our WHMCS was making way to much request to theis license servers and thus my ip was restricted.

But that doesnt tell me what was wrong. Maybe a directory change 2 or 3 weeks before had something to do with it...

Since it's their routine that checks licensing and we don't have access to edit/affect that, I'm curious as to why they left it as your fault.

They definitely changed something. We're seeing this as well. Same goes for all their license servers from a-f.licensing.whmcs.com.
This is a mess. We have some unusable WHMCS installations and they blame us, lol.

Since I don't see it on older installations, I'd have to guess that they possibly (accidentally?) changed the license routine to check on more than a daily/weekly schedule, assuming it's run/triggered via the "every minute" cron.

I think we might've solved our issue.

WHMCS told us that many requests came from domains that weren't allowed (like mail.domain.com instead of domain.com) and requests directly to the WHMCS installation's IP address. Since these are invalid, the request to the WHMCS license server fails - and when enough of these requests has failed, requests from our IP are temporarily blocked. This causes slow load times and the license error.

In each of our WHMCS installations  .htaccess, we've just created a RewriteRule that redirects traffic to the domains that are allowed for WHMCS.

It seems that some Cloudflare IPs are being blocked.

172.67.4.33 is a Cloudflare Ip

If you’re using Cloudflare, follow these steps:

1. Disable Cloudflare Proxy:
   Go to your Cloudflare settings for your domain and turn off the proxy (set it to "DNS only" mode). This will allow your server’s real IP to make the request directly.

2. Update Your WHMCS License:
   Access the following URL to refresh your license:
   https://yourdomain/admin/login.php?conntest=1

This should resolve the connection issue with the licensing server.
