Question

Failed authorization procedure while running certbot

Hello,

When I run this command: sudo certbot --apache -d lazsoc.ca -d www.lazsoc.ca

I receive this error:

Failed authorization procedure. lazsoc.ca (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from https://lazsoc.ca/.well-known/acme-challenge/dKGLJWuycibpj9oI5zkr7oOUXOMpV0cS9QIpNjThQIY [45.55.223.36]: "<html>\r\n<head><title>500 Internal Server Error</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>500 Internal Server Error</h1", www.lazsoc.ca (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from https://www.lazsoc.ca/.well-known/acme-challenge/MKBQljn70jXTDK-VO26lPDF9muXjPbnqtJi__lBYJB4 [45.55.223.36]: "<html>\r\n<head><title>500 Internal Server Error</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>500 Internal Server Error</h1"

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A/AAAA record(s) for that domain
   contain(s) the right IP address.

I’ve scoured the internet for solutions but can’t seem to find any that work. I’m also a relative newbie and am having trouble understanding the system and the problems.

Hello,

It looks like that your site was returning a 500 error and Let’s Encrypt was failing to validate your domain name.

What I could suggest in this case is to check your Apache error log for more information regarding the 500 error:

tail -f /var/log/apache2/error.log

Once you sort out the error with the information from the logs, then you could try running certbot again.

Hope that this helps! Regards, Bobby
