Connection Error

[mmt78]

When I try to node server, I get the error below:

Fatal error: Uncaught ElephantIO\Exception\ServerConnectionFailureException: An error occurred while trying to establish a connection to the server in /var/www/html/shared/socket-io/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php:187 Stack trace: #0 /var/www/html/shared/socket-io/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php(48): ElephantIO\Engine\SocketIO\Version1X->handshake() #1 /var/www/html/shared/socket-io/vendor/wisembly/elephant.io/src/Client.php(60): ElephantIO\Engine\SocketIO\Version1X->connect() #2 /var/www/html/shared/classes/socket.class.php(24): ElephantIO\Client->initialize() #3 /var/www/html/dashboard/news.php(83): Socket->__construct() #4 {main} thrown in /var/www/html/shared/socket-io/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php on line 187

It is strange that when I use Version 2X still I get the same error. Actually it connects the server but throw the error and stop working.

Please catch the exception and dump the content of getErrorMessage().

[mmt78]

getErrorMessage() function returns NULL. When I dump the content of '$e(error)', I get the line below:

object(ElephantIO\Exception\ServerConnectionFailureException)#39 (8) { ["errorMessage":"ElephantIO\Exception\ServerConnectionFailureException":private]=> NULL ["message":protected]=> string(70) "An error occurred while trying to establish a connection to the server" ["string":"Exception":private]=> string(0) "" ["code":protected]=> int(0) ["file":protected]=> string(92) "/var/www/html/shared/socket-io/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php" ["line":protected]=> int(187) ["trace":"Exception":private]=> array(3) { [0]=> array(6) { ["file"]=> string(92) "/var/www/html/shared/socket-io/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php" ["line"]=> int(48) ["function"]=> string(9) "handshake" ["class"]=> string(36) "ElephantIO\Engine\SocketIO\Version1X" ["type"]=> string(2) "->" ["args"]=> array(0) { } } [1]=> array(6) { ["file"]=> string(73) "/var/www/html/shared/socket-io/vendor/wisembly/elephant.io/src/Client.php" ["line"]=> int(60) ["function"]=> string(7) "connect" ["class"]=> string(36) "ElephantIO\Engine\SocketIO\Version1X" ["type"]=> string(2) "->" ["args"]=> array(0) { } } [2]=> array(6) { ["file"]=> string(32) "/var/www/html/dashboard/news.php" ["line"]=> int(98) ["function"]=> string(10) "initialize" ["class"]=> string(17) "ElephantIO\Client" ["type"]=> string(2) "->" ["args"]=> array(0) { } } } ["previous":"Exception":private]=> NULL }

I am using Version2X but why am I getting error about Version1X?

[indigoram89old]

I have the same error...

[Taluu]

Do you also have the result of getErrorMessage() to null ?

[indigoram89old]

Yes, I have

[Taluu]

Which version are you using ? dev-master or 3.1 ?

[Taluu]

Sorry, meant 3.3

[indigoram89old]

"wisembly/elephant.io": "^3.3",

[Taluu]

Could you then try with dev-master ? I'll try to do a release when I'll have enough time to do it...

[Taluu]

And if that doesn't work, could you remove the @ on https://github.com/Wisembly/elephant.io/blob/master/src/Engine/SocketIO/Version1X.php#L196 ?

[indigoram89old]

dev-master is not working

[indigoram89old]

[Taluu]

OK now that is strange. It seems that the resource is already busy with something else (probably socket.io ?).

Could you maybe try a ping on that adress / resource ?

BTW, not really sure but your uri looks strange (it shouldn't be escaped : use_b64=0&EIO=...) but maybe it's the error message that does that.

[indigoram89old]

yes, the error message does that

[indigoram89old]

I try the same code on the server (DO) and it's working.
But I have the error on my local machine (mac os).

[Taluu]

Got no clue then on why this happens, especially as I don't have a mac. Sorry :/

[indigoram89old]

Thanks anyway and good luck!

[peter279k]

I change the socket IO server dependencies and it's worked successfully.

It can look at the PR #186 to know more details.

[indigoram89old]

Wow, I have found my mistake!

The trouble in ini_set("default_socket_timeout", -1);

This line was in another package which uses the elephant.io package.

Thank you guys!

[peter279k]

I think we don't let the default_socket_timeout be-1 because this will always try connecting the socket server until the connection is established.

I have the same error. Even more, this error occurred accidentally, I didn't change anything. Everything works fine in localhost, in NodeJS, in browser ... But the real server doesn't accept any connections from PHP Client. It's so weird, I have no clue.

[akshayb007]

Hii there,

I am facing the same issue in ubuntu with php8. Everything is working fine in nodejs and browser. But not working when emit the event from laravel php.
