Solved - see reply below. This is regarding the ISPconfig API. This is a sandbox, non-production implementation. Don't pick on me for posting passwords, URLs, etc. Problem I get "SOAP Error: Could not connect to host" when I try to connect to the SOAP API. Background To get started I: 1. Created a remote user with admin / admin as my username and password. This matches the username and password I use to log into the web portal. 2. Copied the login.php and soap_config.php files from the remoting_client folder of the installation files. 3. Changed these values in soap_config.php: $soap_location = '[https - I can't post threads to this forum with links so I'm doing this]://10.5.14.35:8080/remote/index.php'; $soap_uri = '[https - I can't post threads to this forum with links so I'm doing this]://10.5.14.35:8080/remote/'; 4. I made the world's simplest .php file to run the stuff: see attached (FYI - the php files are in a folder called 'php' & I don't think it's a path problem because the SOAP request is made). . . . ? Does anyone know what I'm missing?
