Allow public access to a web folder .well_known



To validate a let's encrypt certificate, i need to drop a specific file on the website of my prtg ( http://my_prtg/.well-known/acme-challenge/xxxxx )

I can put this file in the directory C:\Program Files (x86)\PRTG Network Monitor\webroot\.well-known\acme-challenge , but my problem is that i do not know how to allow public access to this folder... if i try to reach http://my_prtg/.well-known/acme-challenge/test.txt , i'm redirected to http://my_prtg/public/login.htm?loginurl=%2F.well-known%2Facme-challenge%2Ftest.txt&errorid=0 with a login page...

How can i configure the prtg web server to allow public access to /.well-known ? (like /images directory for example)

prtg ssl-certificate webserver

Hello there,

I'm afraid these files without extension cannot be used with the PRTG web server. Most customers are using a wildcard certificate for the domain or you can use a Reverse Proxy With IIS and "Lets Encrypt": https://blog.ligos.net/2016-11-14/Reverse-Proxy-With-IIS-And-Lets-Encrypt.html
