Around 11am CST today, our Let’s Encrypt client (using acme-client) started receiving error responses from Let’s Encrypt of these two formats:
Fetching https://ourcentralvalidationserver.com/acme-challenge/SZhujNBrHQdPUTEj3_DqMAJZ46nJxjUwRJjdkD7o4BI: Error getting validation data
Fetching https://ourcentralvalidationserver.com/acme-challenge/Q5Qy0neRk0e3EqGKLJvib7BeQJ4LrkyoLKogR1LuNSU: Timeout after connect (your server may be slow or overloaded)
We are using version 0.4.1 of acme-client. Docs here: https://github.com/unixcharles/acme-client/tree/0.3.7
These errors show up in parsing the response to:
challenge = acme_client.challenge_from_hash(challenge_data) status = challenge.verify_status
Our logs continue to show that our central validation server returned a 200 responses to these requests within 100 ms. Can anyone tell us the timeout length so we can check if response times are too long? Any other ideas?
