I need help troubleshooting a problem

General information for the business: personal
Description of requirements/functionality: Hello,

I have installed software called Bitrix on my hosted server. It requires installing nginx-push-stream module as a prerequisit for some functionality. I was able to successfully install it but I am getting errors indicating the configuration is not set up properly. I am new to nginx so I need someone to help guide me through the causes of the problems, troubleshooting and solution. I will carry out the work myself

I am getting three error messages:
$MESS["MAIN_SC_PUSH_INCORRECT"] = "nginx-push-stream module functions incorrectly.";
$MESS["MAIN_SC_NO_PUSH_STREAM"] = "nginx-push-stream module is required to show comments in real time but not configured properly.";
$MESS["MAIN_SC_NO_PUSH_STREAM_VIDEO"] = "nginx-push-stream module is required to make video calls but not configured properly."

The file with the code which is calling throwing these errors is site_checker.php (attached)

I need someone to check the code and guide me as to what is causing these errors and help me find the solution.

Thanks
