Market Place Can't Load Sometimes

I see this while I have full access to WiFi. And my speed is great, but somehow Marketplace stop loading.

And because my Skin also need Marketplace to load, my skin didn't Load.

You can see I open friends tab and Realms tab, but both loaded? I think it's a real issue.

Sorry I can't really explain why, and how this happens, but the Screen Recorder should show you the issue.
