Cannot subscribe on realm plus on windows

Hi I tried to subscribe to a Realms plus subscription for bedrock edition from the marketplace. When I hit the subscription button I get a pop-up window saying that I lost connection to the marketplace but I didnt lost internet connection and I can buy other stuff from the market place but not that subscription. This error happen several time even after I restart my computer and check my internet connection

I am not sure it's relevant but I had my Mojang account from back in the day ~2012 and only transfer recently to a windows account and had access to the bedrock edition of the game.
