Getting site under construction message after azure webapp deployment

Question

I had a network failure while publishing (using visual studio webdeploy ) my webapp to azure. Later i tried again, Then i got the below error message.

Error 5 Web deployment task failed. (Web Deploy cannot modify the file 'NewRelic.Agent.Core.dll' on the destination because it is locked by an external process. In order to allow the publish operation to succeed, you may need to either restart your application to release the lock, or use the AppOffline rule handler for .Net applications on your next publish attempt.

So i restarted my webapp several times, but same exception. then i tried with FTP. That was also a failure. After few minutes i tried again with visual studio web deploy, then publishing succeeded. But now i am getting a 503 error- site under construction. Any idea?

Note: I tried app offline also. No hope

Answer 1

I resolved my issue. Solution was to remove offline html (APP_OFFLINE.html) from root directory(on server) that is created because of the app offline rule i added to publish profile.

actual problem : <EnableMSDeployAppOffline>true</EnableMSDeployAppOffline> in your publish profile that is actually used to take your app offline while deploying. After finishing deployment, MSDeploy tool should delete APP_OFFLINE.html automatically. But, somehow it did not happened in above case.

So what I suggest is, take a look at the root directory of your website and if there's a file called APP_OFFLINE.html, just remove that.
