Dear community, today, I installed a new router, and set everything up. Unfortunately, my external IP changed. When I try to connect to my Raspberry Pi running an apache server with a Let’s Encrypt certificate using the new IP, it’ll show that my certificate isn’t valid. What would be the correct steps to get a valid certificate now? I’ve tried renewing, but that didn’t work.
I fixed it by waiting a bit longer.
Certificates are not bound to ips. they are bound to hostnames.
