HTTP Error 503. The service is unavailable
- by user1671639
I'm struggling to setup the environment in IIS8, I searched a lot but couldn't find a right solution.
I checked the error logs, but no idea.
C:\Windows\System32\LogFiles\HTTPERR

GET /favicon.ico 503 2 AppOffline qa.hti.local
Then in Event Viewer:
WARNINGS:

I don't understand what the warning means.
ERROR: Application pool 'qa.hti.local' is being automatically disabled due to a series of failures in the process(es) serving that
application pool.
Note: I learned that consecutive 5 failures leads to APP Pool crash, and this can increased. I also tried increasing this but no success.
OS: Windows server 2012
IIS Version: 8
