How to configure Bolt browser to avoid error, "Failed to construct 'WebSocket': The URL 'ws://:7687' is invalid."

Question

Using Neo4j 3.3.0, which just self-upgraded tonight and suddenly the Bolt browser is giving the error:

"Failed to construct 'WebSocket': The URL 'ws://:7687' is invalid."

when I do a simple test command of:

MATCH(n:Node) return n 

It was working perfectly for weeks and I can't get back in as a result. I am using Flask and py2neo as well, but the problem manifests in the Bolt browser.

Was there a config that was overwritten?

Answer 1

I faced the same issue. The issue seems to be only with the neo4j browser.

Open up your browser of choice .

go to http://localhost:7474/browser/

it works fine there. Possibly go through this for the reason https://github.com/neo4j/neo4j/wiki/Neo4j-3.4-changelog

I hope they fix this soon.
