Hi,
My application is down since yesterday. Application is deployed in an Azure App Service since december 2017. I never had a problem with it ; everything was working well since yesterday.
Today, my customers can't connect to the app with error IIS 502.5.
Host is not able to start.
I have following error in azure log : Application 'MACHINE/WEBROOT/APPHOST/NAME-APP' with physical root 'D:\home\site\wwwroot' failed to start process with commandline 'D:\home\site\wwwroot\ELEVEN_SOFT.NAME.Web.Host.exe ', ErrorCode = '0x80004005 : e0434352.
And on latest application log, I found following exception ; this exception points out that a file is not found but it is present in file system (no change has been done) it also mentioned an error on startup.cs line 141 which is code line
await next();
I googled these errors and it could be link with a .NETCORE version issue on server... but I didn't change anything on Azure portal.
Can you please help me to solve this ?

@Ricavir, have you contacted Azure about this problem ? I found a similar problem on the web, your problem might be similar.
In my case it was the Identity used in the pool. The Default does not work

Yes support with Azure is on going. The stange thing is that the App was working well and I did not deploy a new version or something else. And this morning not working ?!
I will give a feedback when this issue will be solved

Thanks @Ricavir. I suspect that something on the azure side has been updated.

Hi,
Just to give a feedback on this. @ismcagdas : you were right ! It was an Azure issue.
After a lot of tests with microsoft support, we ended up by creating a completly new serviceplan and after a fresh deploy, everything was working again.
I didn't had precise explanation of this issue with them but it seems that all Azure ressources should be located in the same region (was not the case before for my app)

Thanks a lot @Ricavir, it is reall hard to identify such problems. I'm sure this will help others :).
