Certbot renewal failure

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:
intellix-fact.com

I ran this command:
certbot renew

It produced this output:
Traceback (most recent call last):
File “/usr/lib/python2.7/site-packages/certbot/crypto_util.py”, line 334, in _load_cert_or_req
return load_func(typ, cert_or_req_str)

An unexpected error occurred:

Please see the logfiles in /var/log/letsencrypt for more details.

My web server is (include version):
Apache2

The operating system my web server runs on is (include version):
CentOS 7

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):
Yes
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): certbot 0.31.0

Hi @intellixfact

a certificate file must start with

-----BEGIN CERTIFICATE-----

Check your certificates with an editor to see, if this is correct.

There should be no BOM (Byte Order Mark).

Hi Jürgen,

Thank for your feedback. Indeed I checked the certificate file with openssl command and it didn’t found any error. So finally I removed all the files and generated new ones and now everything is working fine.
