In short, you can access your UDM Pro with https://unifi.local and make the security warning go away.
I have been using my unifi hardware for some time at home now and I love it. The one thing that kept being annoying is accessing the cloudkey software over SSL. It always returning this warning: And if you approved and continued you still got this icon in your browser:
I was reading Scott Helme’s blogpost how to setup SSL. Sounded like work and I wasn’t sure if that would survive an cloudkey upgrade.
What I noticed when I double clicked the cert when accessing my UDM Pro dashboard: So the CK certs is for https://unifi.local when I tried that address I got a warning the CA wasn’t trusted.
I SSHed into my cloudkey and navigated to /mnt/data/unifi-os/unifi-core/ and found the unifi-core.cer file. I copied that to my machine and double clicked it. You can copy the file to your machine by using this command:
scp email@example.com:/mnt/data/unifi-os/unifi-core/config/unifi-core.crt .
Double click on the crt file (on Windows) and click on install certificate:
Select local machine:
and select the Trusted Root Certification Authorities store:
From now on, navigating to https://unifi.local won’t give you a warning. You might want to add the entry in your DNS if it doesn’t resolve. I added it to my pihole just in case.
On every machine you want to administrate your unifi network you have to add the crt file.
