Steps to reproduce

1. Run Nextcloud Talk client on Mac on local network (The same network as nextcloudpi on Raspberry Pi)

Expected behaviour

It should accept my Let's Encrypt certificate as it does when I'm connecting my mac over my phone or other network.

Actual behaviour

I get Untrusted certificate warning, when I start the client, and it comes back every now and then.

I should add that my iPhone client does not have this issue. Neither accessing through browser (Google Chrome or Safari) or the iPad client running on my Mac.
