Hi,
first of all, thank you for bringing together UBTouch devices and Nextcloud.
I'm working at an academic institution and when logging into the institutions NextCloud server, I am always being asked if its non-trusted certificate should be accepted. I'm afraid that this is the reason why UBSync doesn't let me log in, right? In other words: UBSync still doesn't have a feature to log into self-certified servers. If so, is there a workaround?
I'm on a Nexus 5, UBTouch is fully updated and I have downloaded the actual version (0.6) of UBSync from the store.
