Changing Domain Name


I installed lets encrypt on my Raspberry pi 3 board running apache2. Certbot ran fine and I was about to get a cert. The site works great.

I am going to change my dynamic dns name to a new one. Every time I try to reinstall a cert, it tells me there is an error. I used the --installer apache switch to get this done the first time.

What would be the right way to get a new cert with the new domain name?

If more info is needed, please let me know.

Thanks in advance.

That depends on the error, of course.

If you can share the full output of Certbot, your old and new domain, we can advise you on what to do.


Try adding this flag to your command:

-a standalone

That did it. Thank you so much for your help and quick response.
