c# - Deploying site to IIS server -
i developing mvc site in vs 2013 using 4.6.1 framework. need deploy site remote desktop iis server.
but after deploying, site responds 503 error
steps followed: created application pool version 4.0 verify if iis has 4.6.1 installed. location: hkey_local_machine\software\microsoft\net framework setup\ndp\v4\full , checked release data (has value 394271) created new site , converted application. created new virtual directory , pasted code project (publish setup done).
problem: when try access site, responds 503 , app pool stops. have disabled app pool-> advanced setting ->rapid-fail protection -> enabled false app pool seems stop still.
my error log reason appoffline. have gone through code, (which when run on local dev machine works great) not sure how identify cause of problem.
what possible causes above problem on iis.
see this.
your web pages served application pool. if disable/stop application pool, , tries browse application, service unavailable. can happen due many reasons,
- your application may have crashed [check event viewer , see if can find event logs in application/system log]
- your application may crashing frequently. if app pool crashes 5 times in 5 minutes [check application pool settings rapid fail], application pool disabled iis , end getting message.
in either case, issue worker process failing , should troubleshoot crash perspective.
