Since the beginning of new year, I noticed that all my steem apps based on steem.js don't want to work. After a little research I found out that the public node does not work anymore.
Also I have tried wss://steemd.steemit.com, wss://steemd.steemitdev.com, wss://node.steem.wsand had negative results.
If you are steemt dev and have the same trouble with your app, please try next:
Update to new v0.6.4 version your steem.min.js by link https://github.com/steemit/steem-js/releases
Set socket connection to node

Good news for those who still use my apps they are working and accessible by links WhaleSonar and upVoters
