I'm experiencing a lot of Secure Connection Failures using TBB in China recently. The browser has problem loading all plain network webpages, here's the message displayed in the browser window:
I tried to refresh the page, use new identity, use various of bridge mode(obfs4, meek,etc), even chaining my TBB after a working VPN(psiphon\Free browser, etc), non of these measures work. The problem is so bad that no pages can be loaded. What should I do now?
