Hi everyone,
Recently i'm developing an Android app that able to create ticket via osTicket API.
But in the system logs the system return API error 401.
This system is installed at website hosting provider web server, using shared IP address with subdomain (eg. helpdesk.domain.com).
Is it wrong to use shared IP address for the API key? Or I need to use localhost address (127.0.0.1)?
I'm much appreciate for your kind help and guidance.
Thank you very much.

My understanding is that the API key is tied to the IP address that the traffic is coming from to the ticket system.
