Can not load workspace with Error 428: Precondition Required


When I want to login into my workspace ‘‘demo-project’’, it alway still at the loading screen
And I noticed the console in the Chrome Developer Tool, it reported ‘Error 428: Precondition Required’.
But the HTTP request returned this (in picture)

I have something important in it, but I can not access them now


Still trying logining into my workspace …


on which workspace do you see this error?


the default, “demo-project”


could you check it it’s back to normal?


yes, it worked normally now, thanks
