The SSL Certificate for one of our apps had expired and did not get renewed. I’ve confirmed that my DNS configuration is correct and also recreating the certificate but that didn’t help.
Luckily, only my testing environment is affected, but I would like some help to bring it back online.
This appears to be failing because there’s a TXT record at _acme-challenge.<yourdomain>. We aren’t able to validate when that’s in place. Will you delete that txt record? It should clear up within a few hours once it’s gone.
Thanks, strange that it wasn’t just ignored even when I had the optional CNAME record set up correctly.
LetsEncrypt checks the TXT record before anything else, sadly, the CNAME stuff is lower priority. 
We should catch that and error when it happens though. It’s not too terribly hard.
