File not found?

I am trying to create a certificate for IIS, but I got an error file not found, but when I use the URL it is available. When I run the tests all is OK.

l I get this error message:

2018-11-19 13:08:49.222 +01:00 [INF] Validation of the required challenges did not complete successfully. Invalid response from http://gso.nl/.well-known/acme-challenge/2C0BGu_A3Cv3HdnB9I5uUI49tFx3PaiNLe52CyVa8a0: “\n\n404 Not Found\n\n

Not Found

\n<p”

But when I use the URL’s it does work.

Why do I get this file not found error?

What can I do to solve this?

Hi Hans, are you on the latest 4.x version of the app or is this still V3? V4 has an optional built-in method which circumvents the need for IIS config changes.

When I try those urls I get an error 500, rather than a 404.

For V3 and below your website needs to allow access to the .well-known/acme-challenge path and it needs to allow serving extension-less files. If you also have a custom app or content management system that can complicate matters due to custom handlers etc.

Hi

I am using version 4.010.

I see the app is creating a temp file in the folder E:\Internet\www\www.gso.nl.well-known\acme-challenge, and it fails to do the test test, and after that the file is removed.

But when I try to do a test like this manually (using www.sslforfree.com), the files are still there and can be acces from the suggested URL. But because this website has the same problem (file not found error), there must be something wrong with my IIS config, and I am trying to find out what is worng.

So this is an old test file, also a 404 file not found error, but in chrome it works

I do not see what the problem is.

Hi,

https://letsdebug.net/gso.nl/8669

It looks like your IP v6 AAAA record that points to a different server.

Top, thanks, that was the problem!
