I have 3 servers that since updating have started snowing a few issues.
One that I noticed this morning is that Let’s Encrypt is failing to auto renew. This is the email I get:
An error occurred requesting a new certificate for www.domainnamehere.co.uk from Let’s Encrypt : Web-based validation failed : Failed to download chained certificate : Failed to lookup IP address for letsencrypt.org
DNS-based validation failed : Failed to request certificate :
Gave up waiting for validation
Can anybody suggest anything I can do?
Can these be manually renewed?
