blockchain.stream_from nodes?

[devopsjourney1]

im not having any luck with blockchain.stream on any node...

Is there a list of nodes that support this functionality?

Please specify what failed. A snippet of your code and the output showing the error would be helpful. For sure it works. :smile: Tested recently against rpc.buildteam.io, api.steemit.com & rpc.steemviz.com.

it just sits there forever and doesn't do anything... like it's not finding any posts Edit After like 5-10 minutes it errors out. Added error at bottom of post

This is code that used to work, i've had to swap nodes a few times but since Feb 17th I haven't been able to get one that I can stream from properly..

Any ideas on what's wrong with my code? I'm just trying to find random posts.

custom_instance = Steemd(nodes='rpc.buildteam.io')
b = Blockchain(steemd_instance=custom_instance)

stream = b.stream()
for post in stream:
     if 'title' in post:
          title = post['title']
          print('title')

I think nodes should be a list, not a string. This works for me:

>>> from steem.blockchain import Blockchain
>>> from steem.steem import Steem
>>> s = Steem(nodes=['https://rpc.buildteam.io'])
>>> b = Blockchain(s)
>>> for post in b.stream():
...     print(post)

I failed with nodes list ['127.0.0.1:8090']

[devopsjourney1]

this is still an issue.

Will look into this issue this week.

Hey, Is this still an outstanding error? I get it too.
