I got the renewal reminder email. I'm trying to renew for the first time.
Note that about two weeks ago I changed ISPs from AT&T to Comcast.
Unfortunately, the new router doesn't let me access my site by host name www.jtlanguage.com from within my home network.
But I can reference my site on my phone with the data connection.
I can access the challenge file on my phone, though it does get redirected to https.

Check in a browser to see if the answer file is being served correctly. If it is, also check the DNSSEC configuration.
Authorize failed: This could be caused by IIS not being setup to handle extensionless static files.Here's how to fix that:
1.In IIS manager goto Site/ Server->Handler Mappings->View Ordered List
2.Move the StaticFile mapping above the ExtensionlessUrlHandler mappings. (like this http://i.stack.imgur.com/nkvrL.png)
3.If you need to make changes to your web.config file, update the one at C:\Tools\letsencrypt-win-simple-master\letsencrypt-win-simple\bin\D
ebug\web_config.xml
