"No authentication header supplied." error while running cypher from neo4j browser - neo4j

I found similar questions online but in the context of java code. I am facing this error while running cypher from the neo4j browser. I have to run the same cypher several time, until accidently it gets executed. Rarely query runs in 4-5 attempts, in most cases I have to try 20+ times. This is how it looks in the browser:
The error continues after running :server connect too. How do I fix this once forever. I am fed up rerunning cypher...
Added: I am using Neo4j CE 3.0.4. Can it be due the fact that I might be using databases created in old versions?

Neo4j-enterprise does not allow deletions

I have been having this error for a while:
The environment I am using is:
Neo4j-enterprise 4.1.0 (AWS Ami ami-02a68ff704cf9a737)
I am trying to do a DETACH DELETE for cleaning up some nodes and I keep getting this error:
Neo4jError: Writing in reading access mode not allowed. Attempted to write to internal graph 0 (neo4j)
I have tried several things:
set flag dbms.read_only=false
create new users with permissions.
Signup for the startup program of neo4j with the same email I am using in AWS.
At this point, I am quite lost. I have to check many resources but I do not find the reason of this error.
Do you have any clue about this problem?
Thanks in advance!
I discovered the problem. It was nothing related to the Neo4j setup or with the configuration.
The problem is produced by an ORM I am using in JavaScript, Neode. I was using the function query, and it seems for some reason I had to use writeCypher after version 4.1.0 of Neo4j.

Why doesn't Neo4j show any system information (:sysinfo) in the browser?

I recently upgraded to Neo4j 4.0.6. (Community Edition)
After upgrading my "old" Neo4j database the browser :sysinfo command (Chrome and Safari) doesn't show any information. It just displays the empty tables for Store Size, id Allocation etc.
All the tables and labels are shown as in Neo4j 3.x but no values are prompted. It doesn't matter if I change the "Use Database" settings (switch to system and back) or if stop and restart the server. No entries for :sysinfo show up.
Any idea how to reactivate the DB :sysinfo in the browser interface again is greatly appreciated.

I tend to think its an issue with recent versions.
It caused me to believe a multi upgrade store was incorrect.
So I went the long 'dump to cypher and reimport' route.
After node import, sysinfo was working (4.1 CE)
This behaviour appeared when I added relations
CALL db.schema.visualization() is broken too (no graph tab)
What a time loss, I tell you.
Wont count the days
Somewhere I read to reset the indexes, be sure btree was used.
No, it didnt work.
your next move is to file an issue
It seems ppl also have this issue since 3.5 w/ clusters

SSIS - error in ExecuteSql task

In SSIS, I am running a stored procedure in an ExecuteSQL Task. It is erroring out with:
Executing the query "EXEC [dbo].[mySP]" failed with the following error: "The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I don't have any parameters or resultset.
I was getting this same error. I had a Master Package that was executing multiple individual packages. I thought it was a permissions issue of some sort at first because those 2 packages were the only ones touching a different schema. Wrong. Turns out those 2 packages were the only ones in the entire Master Package that weren't serial in nature (were running concurrently). After I made one package run and complete before the other everything started working.

neo4j browser query (not webadmin) not displayed

In Neo4j When I execute a query in a google crome browser (last version, browser page not webadmin),
often do not I see the results of the query. Then a force of one, two, three .... rerun, it works.
how so this?
thanks

this is some error by devtools : http://s28.postimg.org/5upud8e19/error.jpg
In firefox all work fine!!! Why?
Double check if this is happening with the latest Neo4j version (2.1.4 as of today). If the problem persists maybe start of with a fresh browser profile, e.g. by using the --user-data-dir command line option. If you still get the error, file a issue at https://github.com/neo4j/neo4j/issues/new

Trying to use periodic commit, Neo4j 2.1.2 refuses to run cypher queries

I am working with large node and relationship files of several gigabytes each, so not using periodic commit isn't really an option. I've tested LOAD CSV and it works fine with smaller files on Neo4j 2.1.2, however, when I try to run something like this:
USING PERIODIC COMMIT
LOAD CSV FROM 'file://localhost/C:/dev/project.csv' AS line
CREATE (:Provider { Code: toInt(line[0]) })
The shell refuses to execute, instead displaying a red-background message "Type :help for a list of available commands." This confuses me because normally when I do something wrong, the shell doesn't hesitate to throw a syntax error message below.
OS: Windows 7
