I need help my hidden modpack- friends can't launch

[hyperwaffle]

So I made a hidden modpack just for me and my friends and I sent a friend  the platform address and everythings fine but right before it gets on it kicks them off. However it works just fine for me. Does this have something to do with the modpack being hidden? My friends could use my hidden custom modpacks before. Please tell me what I am doing wrong.

Ok so I tested with another friend and it worked for him.

Only one friend having trouble and he was in my house on the other computer.

Could that have something to do with it?

Without the launcher log (or crash log if one exists) not much can be done about that other instance of it failing. Also, a modpack api url is preferred but may not be necessary depending on the logs.

 

Getting Crash Logs
* Run Technic Launcher
* Select modpack
* Click on the Cog icon located on the bottom left of the modpack logo
