Update Account Malfunction

A couple of days ago, I was on my friend's realm without a problem. However, I took a trip to Italy and tried accessing the world from here, and right when I click on realms, before the screen where it lets me pick what realm I want to play on, this message pops up. I tried clicking each of the buttons, and followed all the steps I was supposed to. The web page said that I was all good to go, but either I am missing a step or it isn't syncing correctly to the Minecraft servers, or my computer. What am I supposed to do? Thanks for the help and let me know
