Local and external access - certificate


Hi everyone :slight_smile:
I just start my adventure with univention.
I had connect my univention server to MS Windows AD with .local name.
Everything works good inside network.
But i wont to have external access to univention and etc., like NextCloud and Collabora. And then i use my external address.
Of course it is problem with certificate.
What i should to do ?

Second question… can i change certificate for univention and apps to my sslforfree.com cert?

Thanks for Your help :slight_smile: and sory … my English is bad :frowning:
