How to configure server (maybe any permission issues) to connect stream Lab (streamlab.io) with laravel application

i tried to implement a real time notification system using stream lab service. locally it works fine. i include a StreamLab.js file provided by Stream Lab service to connect my online app with it. locally it connected with stream lab but on server site it shows a 500 Internal Server Error.

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

i am using go daddy server domain & hosting. is there any suggestion related server configuration to allow connect my server to stream lab?

thanks in advance
