Trying to renew SSL Certificate: Authorization for the domain failed


I am attempting to renew SSL Certificates on my websites. It has been working automatically up until now, but now I am getting this error when I attempt to renew my certificate:

Error: Could not issue a Let’s Encrypt SSL/TLS certificate for Authorization for the domain failed.

Invalid response from
Type: urn:acme:error:connection
Status: 400
Detail: Fetching Error getting validation data

At first I thought it could be that I was reaching my rate limit for the week, but I have tried again unsuccessfully first thing Monday morning, so I am not sure if this is the case anymore, unless the server is automatically attempting and failing to renew the certificates over 20 times within a few hours.

Does anyone have any insight into this? I am a web designer and do not have much knowledge about this stuff and my systems administrator is difficult to get a hold of and unhelpful when I can.

My two domains are: (I deleted this SSL Certificate in an effort to re-install a fresh one. DId not work) (Still has an expired SSL Certificate)

I ran this command: I cannot run commands (via terminal)

It produced this output:

My web server is (include version): Linux

The operating system my web server runs on is (include version): I am not sure

My hosting provider, if applicable, is: Rackspace

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): Plesk Onyx


Look closely, the domain name is appended with “.well-known/”, this cannot work. You most likely have a misconfigured redirect from http to https (slash missing in redirect target).


Thanks so much for that info, you are correct, I indeed had it set up like this.

I am now getting this error:

Error: Could not issue a Let’s Encrypt SSL/TLS certificate for

The “Failed Validation” rate limit has been exceeded for Let’s Encrypt allows no more than 5 authorization validation request failures per account, per hostname, per hour.
See the related Knowledge Base article for details.

According to the error, the failure rate limit resets in an hour, so I will test this again in about an hour and follow up here again.

Thank you for the quick response, greatly appreciated.


This has fixed the issue. Thanks :slight_smile:
