Forbidden 403 Access URL API in Laravel

Good afternoon, let me ask
I created a service API using Laravel, but one of the API urls when I sent the response parameter was 403 or Forbidden. even though before it was fine, it worked smoothly. And I raised it to the server instead it became Forbide. Anyone know why? thank you for answering
If it is ok on local and getting a forbidden error on the server, the problem might be caused by the webserver application. please take a look at this link.

Endpoint Server GraphQL (overblog-GraphQLBundle) Not support Method POST

For 3 Days, my project which worked perfectly locally, once put on the production server.
GraphQl requests are a failure with the error "[Error: Network error: JSON Parse error: Unrecognized token '<']" and after log analysis it is a 404 error because the route was not found.
After investigation via the GraphQl Atlair client for chrome by changing the method to GET to make my GrasphQl requests, the error everything works.
my question is how to work the POST method?
I really need to use the METHOD POST for mutations
Thanks everyone
Very cordially
You forgot to add a trailing slash to your GraphQL endpoint URL.

HTTPS and HTTP shows different results

I'm new to Heroku and I have recently tried deploying my first Laravel project. Howerver, when I opened my app, HTTPS and HTTP yield different results. Particularly, HTTPS doesn't show the right navbar while HTTP does.
To me, this seems quite weird. This is my HTTPS page:
And my HTTP one:
I have found the answer to my question. The reason is due to the disagreement of HTTP and HTTPS in routes of laravel.

Strophe to Openfire: Error during WebSocket handshake: Unexpected response code: 302

I am writing a simple chat client (using strophe) which connects to my Openfire server. Strophe works successfully with BOSH, but for some reason cannot connect using websockets.
I have installed the latest version (websockets-0.0.0.6) of "WebSockets Plugin" plugin for OpenFire, using the default path "ws". My client url is ws://my-server:7070/ws.
I get the following error in my browser console:
WebSocket connection to 'ws://localhost:7070/ws' failed: Error during
WebSocket handshake: Unexpected response code: 302
I look at other related post (stackoverflow.com/questions/22983302/strophe-failed-to-connect-openfire-by-websocket) but have not been successful.
Has anyone come across this problem before?
Any help would really be appreciated.
Thanks in advance.
I'm assuming you were using the latest version of Strophe. The openfire-websocket is developed against with older version Strophe 1.0 . They are not capable now.

Getting updates via xively websockets

I am trying to subscribe to datastream updates via the xively-js javascript library.
However, all I am getting is a 503 error right after creating the websocket:
WebSocket connection to 'ws://api.xively.com:8080/' failed: Unexpected response code: 503
The same error is produced by the xively-js sample-app at
http://xively.github.io/xively-js/sample-app/
Both IE10 and Chrome give the same result.
I can't seem to find any working xively websocket sample. Does somebody have any?
I have found the answer to my own question. It looks like non-secure websockets don't work for some reason.
The secure version wss://api.xively.com:8094 is working fine.
