I tried finding solutions on this issue in your forum’s earlier asked questions, but could not find one. Server is hosted on AWS EC2 with Centos 7 OS and Apache web server. We tried installing letsencrypt ssl certificate on two of our domains using certbot command on our putty cli, but failed.
We installed certbot lib on our server and thereafter ran certbot --apache to install the letsencrypt ssl certificate on our domain:mbracecloud.com, but the following error showed up.
Detail: The key authorization file from the server did not match
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.
How shall we overcome this.
