I am trying to get a certificate for my website using certbot on my PC.
I am running the command:
cerbot certonly --manual
I go through all the steps, but when I have to verify that I am actually owning the server I get a strange error:
The following errors were reported by the server:
Domain: not important
Detail: The key authorization file from the server did not match
To me these strings look exactly the same. I therefore do not understand why it is not working.
Thank you for your help
please answer the following questions. That’s the standard template of #help
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=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
I ran this command:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot):
Your domain is the most important information.
This is probably because you have smuggled a Unicode Byte Order Mark into the first bytes of the file.
If you view the hex:
cat _d7nZ1MkdBFFX0mcMoPYhuMsYn3GMe3LXdPvglYeH3Q | xxd
you would probably see something like:
0000000: efbb bf5f 6437 6e5a 314d 6b64 4246 4658 ..._d7nZ1MkdBFFX
The error message from Let's Encrypt does not include the BOM, because it has no visible representation.
This was probably caused by you using a certain text editor to create the file.
Thank you a lot, I have now used a different editor (nano) and it worked perfectly!
Nice catch @_az That's a subtle one.
