ASP.NET Core hosting - 500 Internal Server Error

username

I'm trying to publish as an ASP.NET Core project using a hosting provider that supports ASP.NET Core. I get a 500 Internal Server Error, which is pretty common. So I searched on the internet and various forums and checked processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%"in the web.config and found that they use the correct translation processPath="dotnet" and arguments=".\MyApplication.dll".

I also checked the connection string and it points to a working production database server. I confirmed the database connection by changing the connection string to the production database and running the project locally. It works and has access to the production database.

I also tried to get the error message (no env related) by using the following in Startup.cs:

app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
app.UseBrowserLink();

I also enabled stdoutLog in web.config, but I don't see that folder either:

stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout"

I also tried changing applicationUrl and launchUrl in launchSettings.json to my prod Url but it didn't work.

So the "500 Internal Server Error" refused to go away, and I still don't have a useful error message. The page only shows:

Oops. 500 Internal Server Error An error occurred while starting the application.

I would appreciate if someone could help me here.

I also enabled stdoutLog in web.config, but I don't see that folder either:

stdoutLogEnabled =“ true” stdoutLogFile =“。\ logs \ stdout”

Here's a trick - you have to create both folders logsand stdoutmanually - and then only then will IIS create a logsfolder inside the log files (not stdoutas you can expect) - don't ask me why because I don't know why ;)


Oops. 500 Internal Server Error An error occurred while starting the application.

Usually this means there is a problem with the configuration in Startup.cs - the most common issues include issues with the database itself, migration issues (if using the Code First approach), appsettings.js issues, social login credentials issues (e.g. missing SecretKey) ...

Please refer to the log file .\logs\stdout- it's the fastest way to find details about the problem :)


app.UseDeveloperExceptionPage（）;

app.UseDatabaseErrorPage（）;

These will work after the WebApp is fully launched, but not when the application is launched.
