SSL install and validation

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., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

My web server is (include version): Nginx

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know): no

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

I was installing SSL cert through a dashboard and I attempted to validate it too many times before the domain had fully resolved. Support has informed me that LetsEncrypt has banned my IP for 2 weeks due to too many attempts. In reading through the forum, it seems like the ban may not actually last that long. Is there a way to monitor this to find out when the ip ban would be lifted?

Hi @aprilIMS

there are some wrong informations. Read

Normal max. limit is one week.

But checking your domain there is no new certificate ( ):

Issuer not before not after Domain names LE-Duplicate next LE
CloudFlare Inc ECC CA-2 2019-07-21 2020-07-20 - 1 entries
CloudFlare Inc RSA CA-1 2019-07-21 2020-07-20 - 1 entries
Let's Encrypt Authority X3 2019-07-07 2019-10-05,,,,, - 6 entries
CloudFlare Inc RSA CA-1 2018-08-21 2019-08-21 - 1 entries
CloudFlare Inc ECC CA-2 2018-08-21 2019-08-21 - 1 entries

Last Letsencrypt certificate is from 2019-07-07.

So you may have hitted the

There is a Failed Validation limit of 5 failures per account, per hostname, per hour.

limit. But this is the most unrelevant limit - wait one hour.

Checking your domain /.well-known/acme-challenge/random-filename is redirected to another domain:

Domainname Http-Status redirect Sec. G 301 0.207 D 200 1.733 H 479 3.907 N
Certificate error: RemoteCertificateNameMismatch 479 4.070 N
Certificate error: RemoteCertificateNameMismatch 301 0.600 D
Visible Content: 301 Moved Permanently nginx 301 0.207 D
Visible Content: 301 Moved Permanently nginx 404 0.287 A
Not Found - looks like this is a domain of your provider to manage Letsencrypt certificate validation.

So wait one hour, then try it again.

I appreciate you and your response. Thanks.
