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.

We'll check it.

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. I also noticed that it doesn't happen when I connect via the guest network of the same router.

Humbly, Ylan

Confirming that accepting (Trust) the certificate in the macOS native certificate dialog doesn't prevent the error and showing the dialog on the next request...
