NextCloudPi: Can't access Web Panel

So my nextcloudpi machine was disconnected for a bit and I just turned it back on again, wanting to get it back into operation. It connected nicely and showed up as expected. I updated to the latest version but there are a number of tweaks I still need to do. Unfortunately I can’t seem to connect via SSH and when I open up the NextCloudPi web interface to enable it I can’t do that either:

# Forbidden
You don’t have permission to access this resource.

I’m running NextCloudPI on an ODroid.

Anyone got any ideas?

Unrelated but also a question: NextCloud is now no longer synching folders when they get too big? That is a bit of an issue since I have a lot of large folders. Any way to change this?
