websocket fail on bitmex

Community Support

Hi Q Gods,

I got into the following issue by trying to connect to bitmex websocket but stuck for days.

h:`:ws://www.bitmex.com “GET /realtime HTTP/1.1\r\nHost: www.bitmex.com\r\n\r\n”

I got the following error:

(0Ni;"HTTP/1.1 301 Moved Permanently

Content-length: 0

Location: https://www.bitmex.com/realtime

")

My other websockets all work except the one above. For example, this is fine.

h:`:ws://ws.blockchain.info “GET wss://ws.blockchain.info/inv HTTP/1.1\r\nHost: ws.blockchain.info\r\n\r\n”

Thanks!!

301 status code tells you that you need to use the new URL as returned instead of the old one.

So what do I need to change exactly? change :ws to :wss?

Correct URL is wss://www.bitmex.com/realtime<o:p></o:p>

Using https://github.com/jonathonmcmurray/ws.q seems to work fine:<o:p></o:p>

yes the right uri is `wss.

still they need to configure the SSL wrapper in order to do this, just fyi
