The FOSSBilling Forum

Hello,

When I first installed FOSSBilling (version 0.6.22), I successfully connected FOSSBilling to my DirectAdmin reseller account.

But now I can't connect to my DirectAdmin reseller account, I'm using FOSSBilling 0.7.1.

When I tried the "Test Connection" button from the System - Hosting plans and servers menu, I got the following warning: HttpClientException: HTTP/2 415 returned for "https://[my-directadmin-reseller-account-host.com]:2222/CMD_API_LOGIN_TEST". (9999).

And this is from the log/application:

[31-Jul-2025 20:42:33 Asia/Jakarta] application.ERROR: Server_Exception: HttpClientException: HTTP/2 415  returned for "https://[my-directadmin-reseller-account-host.com]:2222/CMD_API_LOGIN_TEST". in /home/[my-path-of-fossbilling]/library/Server/Manager/Directadmin.php:754

Please help to solve this problem, thank you.

Hello there,

I checked with our DirectAdmin guy and he said he he hasn't seen HTTP 415 returned by DirectAdmin before.
He was wondering you may have imunify360 setup as he has seen that from other panels when using it?
