Validation Fails - IIS server 2019 - cant be firewall

[danfisher-edgeti]

first time using this in Windows
After looking at logs its telling me error 400 (possible firewall issue)
but I can get to the test site so I know port 80 is working.
I think its having trouble creating a .well-known folder?
because when I go into the site where its to create this, there is nothing there.
but not 100% sure---I've done verbose and its just telling me below

[EROR] [ad.edgeti.com] Authorization result: invalid
[EROR] [ad.edgeti.com] {"type":"urn:ietf:params:acme:error:connection","detail":"20.42.117.120: Fetching http://ad.edgeti.com/.well-known/acme-challenge/VcqXyxKWVJ2cbMs534mQakdY7x1JJqoZSoDgqS_7iJU: Timeout during connect (likely firewall problem)","status":400,"instance":null}

any help would be greatly appreciated!

10 times out of 10 this error means there is actually a firewall or DNS issue. That you can personally visit the url doesn't mean that it's accessible world wide l. For me it also seems to time out.

after it fails, acme wipes out the files so its no longer accessible. I went and made the folders and put index.html in them to test...
http://ad.edgeti.com/.well-known/acme-challenge/ works internally and externally.

No, it doesn't.

But I guess it can't possibly be a firewall issue...

interesting, I wonder why its working for me, thanks for verifying. I'll do some more digging.
