most public Steem full API nodes not function

Hello,

I'm following this post

https://steemit.com/witness-category/@bitcoiner/list-of-public-steem-full-api-nodes-and-example-usage

Using Xeroc python library, I write small script.  It look like all the nodes in the list are timed out to my API call.

Except:

wss://seed.bitcoiner.me

That give not update (old) market asks and bids.

What can be the problem?


Thank you
