Error applicationhost.config HTTP Error 413.1 - Request Entity Too Large

At one point, when you want to upload a backup copy of the database to IIS via phpMyAdmin, an error may appear: applicationhost.config HTTP Error 413.1 - Request Entity Too Large.

The error looks like this:

HTTP Error 413.1 - Request Entity Too Large The request filtering module is configured to deny a request that exceeds the request content length. Most likely causes: Request filtering is configured on the Web server to deny the request because the content length exceeds the configured value. Things you can try: Verify the configuration/system.webServer/security/requestFiltering/requestLimits@maxAllowedContentLength setting in the applicationhost.config or web.config file.

This is due to the fact that there are limits for filtering requests.

I had to shovel a lot of forums, where mostly nonsense is written. Oddly enough, the solution was found on Microsoft website. The decision does not take long.

You must open IIS Manager.

Select a site. Open Request filtering.

Open "Change Settings". Thus, we edit the file in the graphical interface web.config.

Default values:

30000000
4096
2048

I installed in:

We save, enjoy.
