Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=pqm.net), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My web server is (include version): An unexpected error occurred:
There were too many requests of a given type :: Error creating new order :: too many failed authorizations recently: see https://letsencrypt.org/docs/rate-limits/
The operating system my web server runs on is (include version): Debian Jessie
You are currently hitting failed validation limit, which would be refreshed in 1 hours.
There is a Failed Validation limit of 5 failures per account, per hostname, per hour. This limit is higher on our staging environment, so you can use that environment to debug connectivity problems.
Please wait for 1 hour and try again.
P.S. In the meantime, you could try to issue a test certificate with Let's Encrypt staging environment, by adding --staging flag. certbot-auto certonly --server https://acme-staging-v02.api.letsencrypt.org/directory --manual --preferred-challenges dns -d pqm.net -d '*.pqm.net' --staging
