Hi I found a tutorial how to secure ispconfig admin portal (8080), emails and all server functions with letsencrypt. however my server hostname is using my URL that i have a regular SSL installed (under SSL tab) how can i secure my server using my SSL and not letsencrypt? or, can i create a letsencrypt on this site that already has a SSL and use the letsencrypt for the admin portal, emails etc.. thank you
The same principles apply. Simply symlink that ssl certs as demonstarated on the earliest parts of that tutorial instead. The others should be the same except for the incron. There you need to change the LE SSL folder with your SSL folder so that the next time you update that folder, ispserver.pem will automatically be recreated. Restart incron service when you finished setting it up. You can also simply use daily cron job to recreate ispserver.pem instead of using incron. This should work fine as well.
