Letsencrypt issue on CentOS 8: challenge file not written

[ladhani]

I had a very strange issue with requesting a letsencrypt certificate.
The challange failed with error:

Invalid response from http:// -removed- /.well-known/acme-challenge/g859sYD_nyjIpiGQ2FUsL5ANEZ0bIyIpHRHWrNr1XXX

The domain is OK.
Some investigation showed me that the challenge file was not written to the acme-challenge folder.

I googled and found someone mentioning that he had a similar problem and solved it by manually making the folders .well-known/acme-challenge under public_html.

So I tried this and IT WORKED!!!

Anyone else having this strange issue?

My setup:
Clean install of VirtualMin script on a fresh install of Centos 8 minimal.

Server:

Hi,

@ladhani

Some investigation showed me that the challenge file was not written to the acme-challenge folder.

Thanks for heads up.

Indeed, this was a bug that we’ve just fixed.

Hi,

I was looking at that bug right now. I’m also on CentOS 8.
Nice to know it’s a reported bug and has been fixed already.

edit:
@Ilia when will the fix be released? thanks!

We plan roll large new release (including Virtualmin) this weekend.

Thanks for sharing this information. Glad that it was an easy fix on your side.

I can confirm that for my server, the fix of Illia on letsencrypt-lib.pl solves this issue.
Just made a new domain and the server succeeded in getting the LE certificate.

Thank you Illa.

I can confirm that for my server, the fix of Illia on letsencrypt-lib.pl solves this issue.

You are welcome. We will have this functionality in upcoming Webmin release. (with just a little bit better implementation, code wise).
