we can't get oauth token from oauth client part.

[okblue430]

When sent token request in client part. (https://domain.com/oauth2/token using guzzle http request), I am getting this apache log. [30/May/2018:19:38:43 +0200] "POST /oauth2/token HTTP/1.1" 404 10081 "-" "GuzzleHttp/6.3.3 curl/7.60.0 PHP/7.0.30"

this is client token request in guzzle http. GuzzleHttp\Psr7\Request Object ( [method:GuzzleHttp\Psr7\Request:private] => POST [requestTarget:GuzzleHttp\Psr7\Request:private] => [uri:GuzzleHttp\Psr7\Request:private] => GuzzleHttp\Psr7\Uri Object ( [scheme:GuzzleHttp\Psr7\Uri:private] => https [userInfo:GuzzleHttp\Psr7\Uri:private] => [host:GuzzleHttp\Psr7\Uri:private] => happydemy.com [port:GuzzleHttp\Psr7\Uri:private] => [path:GuzzleHttp\Psr7\Uri:private] => /oauth2/token [query:GuzzleHttp\Psr7\Uri:private] => [fragment:GuzzleHttp\Psr7\Uri:private] => ) [headers:GuzzleHttp\Psr7\Request:private] => Array ( [Host] => Array ( [0] => happydemy.com ) [content-type] => Array ( [0] => application/x-www-form-urlencoded ) ) [headerNames:GuzzleHttp\Psr7\Request:private] => Array ( [content-type] => content-type [host] => Host ) [protocol:GuzzleHttp\Psr7\Request:private] => 1.1 [stream:GuzzleHttp\Psr7\Request:private] => GuzzleHttp\Psr7\Stream Object ( [stream:GuzzleHttp\Psr7\Stream:private] => Resource id #167 [size:GuzzleHttp\Psr7\Stream:private] => [seekable:GuzzleHttp\Psr7\Stream:private] => 1 [readable:GuzzleHttp\Psr7\Stream:private] => 1 [writable:GuzzleHttp\Psr7\Stream:private] => 1 [uri:GuzzleHttp\Psr7\Stream:private] => php://temp [customMetadata:GuzzleHttp\Psr7\Stream:private] => Array ( ) ) ) }

But server response is 404 not found. I moved oauth server to different hosting ( CentOS hosting server ). And then I am getting this error.
