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.
