fsockopen unable to connect to 127.0.0.1:9876 (Connection Refused)

[cam-spacebar]

I've installed and configured Sulu on my dev machine (Mac, El Capitan with PHP 5.5)

I can run symfony apps without a problem, however the Sulu install creates this error in logs:

[2016-03-07 18:51:55] php.DEBUG: fsockopen(): unable to connect to 127.0.0.1:9876 (Connection refused) {"type":2,"file":"/Library/WebServer/Documents/test/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Command/ServerCommand.php","line":59,"level":28928} []

I've tried different ports, different sulu installations and done as much Googling possible and I'm unable to solve this problem.

@camburns That sounds like a websocket issue... Does it work if you also run the command app/console sulu:websocket:run -e prod before accessing the website? And have you maybe set the confg sulu_content.preview.websocket to true?

Thanks @danrot. I ran your command and Terminal gave me:
Websocket server started: "ws://sulu.lo:9876/<route>" bound to IP 0.0.0.0

and when browsing 0.0.0.0 on chrome I got the exception: "There exists no portal for the URL "http://0.0.0.0/"

I imagine this exception relates to a domain name issue and I'll need to do some debugging / learning more Sulu.

I wasn't able to find out where to edit sulu_content.preview.websocket. I unfortunately don't have experience around websockets.

Possible solution:
I was able to solve the problem by using the MAC apache server instead of php app/console server:run command, however I suspect many people will be using php app/console server:run to run Sulu and this will throw a lot of newbies off on first install.

@camburns 0.0.0.0 is a wildcard ip. you websocket listen to all ips with the port 9876. you can not brows a websocket in chrome directly.

you can run sulu with the server:run command but you have to run it with the router argument app/console server:run -r app/config/router_admin.php this allows you to use the admin for website use the router_website.php file

I'm not aware of all details but this issue occurs with PHP7 and Symfony Standard Edition. And it's a false positive generated by the following fact: Symfony uses fsockopen to check if the connection is already in use.

It's not a problem, just a standard check from Symfony. (that you can ask why, IDK)

Ah, i see, that's just a debug message... @camburns Is the live preview working for you? In case it is, that is not really an issue.
