Hi,
Our letsencrypt certificate on Azure expired. Every time, I try to renew, I get

The Lets Encrypt ACME server was probably unable to reach http://smandsm.org/.well-known/acme-challenge/WuQiNhAoWoUzslpJ8V-0-9M4rmvdcxidrCyBxOEe-Hg view error report from Lets Encrypt at https://acme-v01.api.letsencrypt.org/acme/authz/Au1Le3D55OxflkrmiCauqOL4MclrBWHs9QAlGVyIFeg for more information

My domain is: smandsm.org

Thanks

You can see the error message from Let’s Encrypt if you click on the https://acme-v01.api.letsencrypt.org/ link in your post.

The domain has these DNS records (from my perspective):

smandsm.org.                                      600   A      40.123.45.47
smandsm.org.                                      600   A      50.63.202.55

And, for comparison, the www subdomain has these:

www.smandsm.org.                                  3600  CNAME  smandsm-wp.azurewebsites.net.
smandsm-wp.azurewebsites.net.                     1800  CNAME  waws-prod-bn1-035.vip.azurewebsites.windows.net.
waws-prod-bn1-035.vip.azurewebsites.windows.net.  300   CNAME  waws-prod-bn1-035.cloudapp.net.
waws-prod-bn1-035.cloudapp.net.                   10    A      40.123.45.47

40.123.45.47 is your Azure thing.

The other IP address comes from GoDaddy’s URL redirect service, which prevents HTTP validation from working. You should probably just disable it.
