Interesting.
This article is showing up for me - https://steemit.com/steemsports-soccer/@steemsports/steemsports-serie-a-juventus-f-c-vs-a-s-roma-mass-sp-distribution-game
If I click on their name on that page, their blog opens just fine. But when I tried through your @steemsports link in the OP, it took me to the error page.

Same error in Canada.

When I go to the wallet, then hit 'blog', then the blog shows up for me.

Very odd why it is only steemsports.  btw the above account (kiwi) is mine and posted that comment when i was testing the browser:)

same error here as well.

I'm in the Southeastern USA and receiving this error as well. I have checked a lot of accounts and this is the only one I'm getting an error on. I hope they get this corrected soon.

I did find an error.  Thank you everyone for testing.  I have opened an issue for it:

Websocket frame size exceeded #874
https://github.com/steemit/steemit.com/issues/874

I am currently in America (California) and I have the same issue.

Same here.

In Germany I get this error too.

I get it too in Scotland

Also seeing a 500 error, midwest USA.

I informed one of the web developers earlier of this post and just now created a github issue: https://github.com/steemit/steemit.com/issues/873

Nobody's seen a similar issue on any other account page, right?

I've seen it show up for a few seconds and then disappear again.  One account out of thousands.. wtf.
