Hey there!

Sorry, I haven't seen your reply. Feel free to poke me then.
The problem is that your server ip is not the same is your request ip.
This may be due to the domain (provider) you have.
The ip address linked to your domain is 104.xxx and your request is coming from 185.xxx
TrackBase is then blocking the request and gives error code 3, unauthorized.

Make sure that your request ip is the same as the ip connected to the domain in your url "Server URL" setting.
