ARR IIS got 503 Service Unavailable every morning of the day

I use ARR feature on IIS to implement the load balancing web application. I have 2 ARR Servers, 2 Web Servers. Every day, on the first time when user accesses the page, he always get the 503 Service Unavailable error. After he pressed F5 key to reload the page a few times, the website started working properly again.

Please help me to fix this problem?

It could be possible that the App pool resources got free while the site has no requests for a specific amount of time.

In that case, when users send requests to the site then it needs some time for warm-up and after that, you could notice that the site works fine.

To avoid this issue, you could try to go to the IIS-> App pools -> Select your site app pool -> go to Advanced settings.

Set Start mode as Always running.

See whether it helps to fix the said issue.
