Failed authorization procedure urn:ietf:params:acme:error:unauthorized ERROR 404

Help

Hi,

recently I can no longer validate domains, with older projects that have already been successfully validated, this error now occurs occasionally when renewing.

I could not find a solution because I did everything necessary to issue a certificate.

so I experimented a little and for me the vHost header of my apache configuration file had to be changed.

VirtualHost *:80

to

VirtualHost MY_IP_ADDR:80

I hope this can help someone who has the same problem.

Without knowing the intricate details of your Apache configuration, this change in configuration might or might not benefit others. As far as I know, if all your VirtualHost sections only contain a wildcard followed by the port number, this change shouldn’t be necessary.
