I use Ubuntu 16.04 with Bash, Nginx, and Certbot and I ran the command
certbot --nginx -d "$domain" -d www."$domain" but this Certbot operation failed due to a misconfigured A DNS record (an issue which is now fixed in the DNS management tool (DNSMT) of the hosting provider).
I wonder how should I proceed after the execution failure due to the wrong A record and after fixing it in the DNSMT.
Should I just re-run the above command? Or should I first run
certbot --nginx rollback, that, if I understand correct, will rollback any change already made by Certbot (this is the only change I did with Certbot since installing the operating system) and only then re-running the above command?
