For whatever reason, you’re not able to serve the challenge file. Are you sure your web server service account has read access to that directory?

Hello Jared

Yes, we have set modify level permission to website directory. Is there any other user to allow permission?

Do you use ASP.NET MVC or URL Rewriting?

Is there a web.config file in .well-known/acme-challenge or the root of your web directory that allows files without extensions to be served? (Like this example. Plesk should do this for you but it may have been accidentally deleted or something.)

Do you use ASP.NET MVC or URL Rewriting?
Ans: we are using umbraco application with URL rewriting.

web.config file is under root of web directory. I can see below line under web.config file.

Also, I have created test.txt file under below directory, but it is throwing an error that Parser Error Message: The configSource file ‘config\umbracoSettings.config’ is also used in a parent, this is not allowed.

Is config\umbracoSettings.config referenced twice in C:\inetpub\vhosts\\zp\web.config? Try commenting out the deeper "child" one.

Also, there are a lot more errors if you click on Show Additional Configuration Errors. It looks like a section may have been copy/pasted twice by accident.

I can see single entry of config\umbracoSettings.config in web.config file. Do you have any other option to fix this issue?

Your test page is accessible now. Maybe some scheduled task from your CMS ran amok?

Try renewing from the Plesk panel again now.

Yes, Lets encrypt certificate has been renewed now and issue has been fixed.
