gzweb and ipynotebook websockets not working in some versions of Chrome

osrf-migration commented 10 years ago

Original report (archived issue) by Brian Gerkey (Bitbucket: Brian Gerkey, GitHub: gerkey).

With some versions of Chrome/Chromium, or perhaps on certain machines, the websocket connections to gzweb and ipynotebook fail.

Further testing suggests that the failure is related to whether the websocket is TLS-encrypted or not. This test page:

http://www.websocket.org/echo.html

allows you to test your browser's websocket support, with a toggle to select whether to "Use secure WebSocket (TLS)."

For me:

in Firefox (where I can connect to gzweb/ipynotebook), I can connect whether or not it's secure.
in every version of Chrome/Chromium I've tried (where I can't connect to gzweb/ipynotebook), connecting without the secure option fails (connecting with the secure option succeeds).

changed state from "new" to "wontfix"

Turns out that it's due in some way to my desktop machine's proxy setup. I have my machine configured to use a local squid proxy. In that situation, Chrome seems to refuse to connected over a non-TLS websocket. Disabling the proxy setting works for me.
