I'm facing serious issue with my ARR loadbalancer.
The problem is, it's unstable.
Sometimes I'm able to launch my application (a gis portal) sucessfully, but sometimes the load balancer fails to launch the application. the browser console shows this error:
Compositor.WebClient.ashx?p=%2fapollo-portal%2fApolloPro.aspx&e=en-US.release.js&t=636987893711144299:2244 Uncaught TypeError: Cannot read property 'loadData' of undefined
Failed to load resource: the server responded with a status of 404 ()
Uncaught TypeError: h is not a constructor
I'm honestly not sure what went wrong since I believe the load balancer has point to the correct url.
the health check returned "pass" for both server nodes.
The application can be launched succesfully from each node's url, but not from the load balancer
Can anybody help me, where to start checking the problem?

Where is this error coming from the ARR server? Or is it coming from the backend server?
Can you app function in a load balanced environment?

Yes, the application can work in load balanced environment. There are multiple webpages, services, and application but somehow it only stuck when launching the portal. Other application works fine
Other than using leansentry (because of safety risk/issue, I cannot use this), do you know how to troubleshoot? I'm very new using ARR
