Hi there,

Based on https://community.letsencrypt.org/t/new-service-busy-responses-beginning-during-high-load/184174, Let's Encrypt is now sending 429 responses back when the requestor is not rate limited, but when the Let's Encrypt servers are too busy.

Will dehydrated-io support this error in that it waits for the retry-after period and then retries, or is it the projects response that all users should implement this retry logic themselves?

Best regards,
Guus

Retries will be supported in an upcoming release but I can't give you any specific time for that. I have a big project ending this month and hope I'll be able to work on a bit of delayed work on dehydrated after that.

There is a very simple config option to get this working:

CURL_OPTS="--retry 5"
