I can't reproduce this. Does the problem still happen for you in an incognito window, with all browser extensions disabled?

If so, what browser are you using, and can you share a notebook where this happens for you consistently?

I had the same problem, in google Chrome. I solved it by disabling the extension Urban VPN Proxy
