I keep getting disconnected from family sharing...

My family has family sharing turned on and everything has worked fine until recently. I keep getting disconnected from family sharing somehow and therefor I don't see family purchases, Apple Music tells me I don't have a subscription and so I don't have access to my iCloud Music Library. I seem to be able to reconnect for a brief moment if I sign out and back in on the iTunes Store, but then I get error 5002 if I try to turn on iCloud Music Library even though my connection to the store is as good as it can be.

I have tried removing myself from family sharing and adding me back in multiple times but I just get disconnected again some days after. Sometimes I can keep connection for some days or even few weeks but then it happens again. Now I don't see my music library, I can't open shared apps, I don't see family purchases and this is getting quite frustrating.
