Desktop (please complete the following information):

• OS: Windows Server
• Version 2022 Standard

Additional context I've tried many different configs, started with one that involved different location for the root directory (not in c:/inetpub/wwwroot, but in i://wwroot, now it is in the default location), windows privilliges cant be the case cause i checked it multiple times, i've added the mime type recognision in web.config like: <?xml version="1.0" encoding="UTF-8"?>

I've also tried many diffrerent configs when it comes to the -w option: -w "c\inetpub\wwwroot" -w "c\inetpub\wwwroot\" -w and nothing seems to make a difference... Also, i've checked some third party validation software like: https://check-your-website.server-daten.de/?q=terminale.krakow.pl and there is someting about DNS problem, i don't get it as the site is available from the outside... One more thing, i checked if wincertes has problems with creting a folder, but don't know, if that is the issue, i've created a folder exactly like: .well-known\acme-challenge (with the right spelling, that was chcecked) and nothing appeared, even with no folder, the wincertes didn't create one
