Good evening,

Just installed the new version (community edition 3.4.9) and I have this configuration at neo4j.conf:

browser.remote\_content\_hostname\_whitelist=\*  
browser.post\_connect\_cmd=play [http://127.0.0.1:80/egov-guide/introduction.html](http://127.0.0.1:80/egov-guide/introduction.html);

The idea is to run a specific guide introducing the database. with previous versions runs well, but with this one I get the following error:

Remote guide error: TypeError: NetworkError when attempting to fetch resource.

Just to complete: if I switch to 3.4.7 or 3.4.8 the educational guide is accessible. This last one is available through IIS and the web.config is like that:

```auto
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
  <httpProtocol>
    <customHeaders>
      <add name="Access-Control-Allow-Origin" value="*" />
      <add name="Access-Control-Allow-Methods" value="GET, PUT, POST, DELETE, HEAD, OPTIONS" />
      <add name="Access-Control-Allow-Credentials" value="true" />
      <add name="Access-Control-Allow-Headers" value="X-Requested-With, origin, content-type, accept" />
    </customHeaders>
  </httpProtocol>
        <staticContent>
            <mimeMap fileExtension=".grass" mimeType="neo4j/style" />
        </staticContent>
</system.webServer>
</configuration>

```

Thanks in advance

Joao Carlos

Thanks for reporting, looks like a regression. Could you please post this also as GH issue to [GitHub - neo4j/neo4j-browser: Neo4j Browser is the general purpose user interface for working with Neo4j. Query, visualize, administrate and monitor the database.](http://github.com/neo4j/neo4j-browser) ? Thx!
