Hey! I have a few things you can try, i found a solution. First, click the "Home" button on your switch or just close out SwitchBru with the "X" button, once you do that come back in BrowseDNS. Try to enter the URL of your choice again, if that does not work continue to close SwitchBru until the problem is solved.
Until then, we'll have our admin team look into the bug.
If you have anymore questions, let me know.
