    Trouble authenticating ACME challenge file

    Umbraco 8
    Umbraco 8

    I’m having trouble authenticating my ACME challenge file in Umbraco V8.

    Looking at the source code here, the appropriate key now looks to be Umbraco.Core.ReservedUrls (but I might be wrong). However, I’ve tested this, to no avail (see below):

    <add key="Umbraco.Core.ReservedUrls" value="~/.well-known/,~/.well-known/acme-challenge/">

    Key points:

    • The generated file is reachable in the browser, so it’s just authorization
    • There’s no re-write rules in my web.config
    • I’ve also tried setting the Umbraco.Core.ReservedPaths key (since that looks like the older V7 key)
    • Process works perfectly in V7 using the old umbracoReservedPaths key

    Any help would be much appreciated!

    Just an update in case anyone encounters this issue.

    The ACME challenge file failed to authenticate due to the fact that the domain name (hosted by a client) pointed to multiple IP addresses.

    Once that was resolved, everything worked perfectly.

    As such, this wasn't an Umbraco issue.
