Let's Encrypt Renew Stopped Working

[tolgaytoklar]

I have been using let's encrypt for two years, Today, i received an error e-mail about renewal process

Error message:

Getting challenge for ribony.com from acme-server...
Waiting for domain verification...
Challenge is invalid. Details: Invalid response from https://domain.com/ [188.***.250.***]: \. Exiting...

I changed nothing. How can i fix this problem?

My DA version: 1.61.0
OS: Centos 6
Custombuild version is 1.1
Apache version is 2.2

Looks like you are on super old code. You need to upgrade to custom build 2. I don’t think smtalk maintains version 1 any more. CentOS 6 goes eol in November, just Incase you not already planning a migration.

Seems you're on cloudflare if I'm not mistaken?

Have a look at this thread, maybe it can be of help.

Let's encrypt Wildcard - Cloudflare

Hi, I had a problem 5 minutes ago and I remembered that I have cloudflare in domain so I copy-paste this TXT (which Let'sEncrypt added in DA) record from DNS and re-run challenge - now it works but now I'm thinking if will it work or I will have to change this dns record in cloudflare again...
