Invalid server upgrade response and bad opcode

[sourcefrom]

Hi,

My code worked fine till about 10 days ago, when I suddenly couldn't connect to a third party websocket server. The following is the error log, various system version info (I redacted a bit just to get rid of some repeated errors).

Upon some invistigation, here are some initial suspcions, but I was unable to pinpoint exactly where the problem is:

third party web server is up and running, and my code worked till 5 days ago
googled "failed: Server sent invalid upgrade response:", but couldn't find actionable clues
Would apprecaite some insights on how to fix this.

Thanks!
