Can't connect to mobile internet with CyanogenOS 13

On Google, I found a similar problem on Reddit, which describes exactly what I've got right now: https://www.reddit.com/r/cyanogenmod/comments/3xm0mo/mobile_data_not_working_cm13/ The problem is that, even though I do have cellular reception, and everything (WiFi, SMS, calling) works just fine, whenever I turn off WiFi (or walk outside WiFi) it doesn't connect to the internet using a data connection (3G/4G etc). What I've tried so far (based on that Reddit post's comments) - Reboot my phone - Toggle Airplane mode on/off - Switch preferred network setting to 3G and then back to 4G - Enable Data Roaming (even though I'm still in the country this should be active) - Going to *Settings>Cellular networks>Access Point Names* and trying each of the available options - Check my remaining MB-credit on my subscription (I still have >100MB remaining) - *this is actually irrelevant since I do not have an exclamation point at my reception-icon* The only thing I haven't tried is some kind of reinstall/rollback of my OS. My Cyanogen version is 13.0-ZNH0EAS45F When I go to my *SIM 1 status*, I see that "Service status" says "Data: In service", but (even though my WiFi is turned off) the "Mobile network state" is "Disconnected". Can I force my phone to connect to the mobile network somehow? PS: This problem has existed for about 2 hours now. Before that it worked just fine. Update: One of these things might have fixed it. I'm not sure. It suddenly started working again, even though between the time of posting and now I did not change anything about my settings *at all*. I have (after it started working) reverted all changes to my settings, and it still works. I have no idea how this worked, but it works.
