Unable to connect to own realm

I try to connect to a realm i created recently and I cannot. My user is BentaOne.

I am on a windows 10 pc using the windows 10 version of minecraft. this problem was in the beta and also in the v1

I am situated in France

I am connecting using WIFI but it says "unable to connect to world". If I use my sons account with the same version of the software but this time connecting from a surface pro 3 machine running windows 10 then it can connect.

If i connect from my work (another location), using ethernet connection then I am able to connect.

given that it works with my sons account on another machine on the same home network I am ruling out issues with ports etc.

There seems to be a direct correlation with the realm belonging to my account and me not being able to get in.

The world on the realm is a world that I had created in local network game with my son. I have tried removing it and creating a new world thinking perhaps the world was corrupted but this is not the case.

Are log files generated? Let me know where and I will provide you with them.

I hope you guys get this fixed soon. I only bought two copies of minecraft and a realm so that I could play with my son.

Kind Regards
