Jolla Tablet, Wifi router specific Internet connectivity issues
For some reason, Android Spotify on my Jolla tablet stopped working when connected to the Internet using home Wifi/ADSL. Spotify says I'm not connected to the Internet. However, I am connected, I can play music using Youtube via the browser. From my router's control panel, I see the tablet has IPv4 and IPv6 IP addresses.
I can also use Android Spotify using my Jolla phone using the same home Wifi access point. From the tablet, using this Access Point, I also cannot open the Jolla store. It says "Problem with Store. Content not available. Please try again later"
When I use Internet sharing using my Jolla (i.e. it then uses my 4G mobile data), and connect my Jolla tablet to it, suddenly it works again. I can also open the Jolla store, everything works.
What could be the problem? What could explain the difference between the table and the Jolla, and between 4G and Wifi.
Note: Spotify on the tablet used to work with the home Wifi. I don't know what if anything could have changed.
