Install and Configure HaProxy LBR:issue in updated platform

I did it twice but got the same error as the below image and it seems every 5th task is giving me an error when I am about to get streak.

Please check and let me know, app server output are below:

Hi @yogendrapratapsingh

Can you please mark the task to review and share the link here

Regard

I wish I could mark, as there are the number of tasks which is happening same.
I do not see any option for marking this review.

I seem to have the same issue:

All app servers answered on port 6300 and the load balancer correctly listened on port 80. The button to show it in browser also returned the page correctly.

The error I received was the same as @yogendrapratapsingh , that stapp01 server didn’t listen on the correct port (in my case 6300 2nd try and 8088 1st try). I have run the lab two times with the same results.

Regarding the “Review” button on the task board, I can’t seem to find it either for any of the tasks.
