I am trying to make a simple chat on RoR, I do this for this video
https://www.youtube.com/watch?v=kJbuZecN1c8
at the stage of checking the connection websocket, the console displays the following error
WebSocket connection to 'ws://localhost:3000/cable' failed: Error
during WebSocket handshake: Unexpected response code: 500
what can it be connected to? What are the possible solutions?
UPDATE:
rails logs raise error:
Started GET "/cable" for 127.0.0.1 at 2018-04- 06 18:19:44 +0300
LoadError (/home/alexandr/.rvm/gems/ruby-2.4.2/gems/nio4r- 2.3.0/lib/nio4r_ext.so: undefined symbol: rb_cFixnum - /home/alexandr/.rvm/gems/ruby-2.4.2/gems/nio4r-2.3.0/lib/nio4r_ext.so)
It was just necessary do gem install nio4r -v '2.3.0'

I'm trying to connect to the Liquid exchange's Stream API with pusher. Documentation here
I have constructed a function that is in line with the Pusher library's documentation. Link to that here
My current code looks like this:
require 'pusher-client'
channels_client = PusherClient::Socket.new('LIQUID', {
ws_host: 'tap.liquid.com'
})
and running that gives me an error message of:
D, [2019-08-20Txx:xx:xx.xxxxxx #xxxxx] DEBUG -- : Binding
pusher:connection_established to pusher_global_channel
D, [2019-08-20Txx:xx:xx.xxxxxx #xxxxx] DEBUG -- : Binding
pusher:connection_disconnected to pusher_global_channel
D, [2019-08-20Txx:xx:xx.xxxxxx #xxxxx] DEBUG -- : Binding pusher:error
to pusher_global_channel
D, [2019-08-20Txx:xx:xx.xxxxxx #xxxxx] DEBUG -- : Binding pusher:ping
to pusher_global_channel
If I try to run this after the first command:
channels_client.connect
...it refuses to connect.
C:/Ruby26-x64/lib/ruby/gems/2.6.0/gems/pusher-client-0.6.2/lib/pusher-client/websocket.rb:17:in
`initialize': No connection could be made because the target machine
actively refused it. - connect(2) for "tap.liquid.com" port 80
(Errno::ECONNREFUSED)
The error comes from tcpsocket.new (Ruby https://ruby-doc.org/stdlib-2.5.1/libdoc/socket/rdoc/TCPSocket.html) in websocket line 17: https://github.com/pusher-community/pusher-websocket-ruby/blob/master/lib/pusher-client/websocket.rb
ws_host tap.liquid.com 80 seems to be invalid, https://pusher.com/docs/channels/library_auth_reference/pusher-websockets-protocol
I have tried using a secure connection, at least in the browser and got a 404 for ws and invalid request, which is good in this case, for https (https://tap.liquid.com/).
You need to configure ssl in the client configuration, but the pusher-client gem as well as one other I have found are pretty old. Maybe it is wise to switch to a more up-to-date library like https://github.com/pusher/pusher-http-ruby/blob/master/README.md
The example contains an option for activated SSL.
1) In the first time, when I deployed the origin code to heroku server with git clone https://github.com/cleverbeagle/pup
The launching application didn't work.
I managed to correct this with to copy the content of 'settings-development.json' file and paste in Heroku => myProject => Setttings => Reveal Config Vars => Key : METEOR_SETTINGS and Value : I pasted here the content.
thanks to :
- https://github.com/cleverbeagle/pup/issues/9
- https://github.com/cleverbeagle/pup/issues/197
So, now, the app is showing on server.
2) On Chrome console, I have this error :
50d72c91808ef7fba57f920b67d152d2d57698eb.js?meteor_js_resource=true:9 WebSocket connection to 'ws://localhost:4001/graphql' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
so I changed this in METEOR_SETTINGS
"graphQL": {
"httpUri": "http://localhost:3000/graphql",
"wsUri": "ws://localhost:4001/graphql"
},
to
"graphQL": {
"httpUri": "https://myproject.herokuapp.com:3000/graphql",
"wsUri": "wss://myproject.herokuapp.com:4001/graphql"
},
Note without https and wss, the app is not showing
3) Now on Chrome Console, I have :
this warning :
50d72c91808ef7fba57f920b67d152d2d57698eb.js?meteor_js_resource=true:9 WebSocket connection to 'wss://myproject.herokuapp.com:4001/graphql' failed: WebSocket is closed before the connection is established.
and after several warning above, I have this error :
50d72c91808ef7fba57f920b67d152d2d57698eb.js?meteor_js_resource=true:9 WebSocket connection to 'wss://myproject.herokuapp.com:4001/graphql' failed: WebSocket opening handshake timed out
By using the origin source code from Pup, I can signup on server but I cannot create a new document.
Any help, please ?
Thank you
EDIT 15 JAN 2019
**4) I remove Port like this : **
"httpUri": "https://myproject.herokuapp.com/graphql",
"wsUri": "wss://myproject.herokuapp.com/graphql"
Now, I can create New document on https://myproject.herokuapp.com/documents
but I still have this warning :
fe6fa1ac83e19aa2513ac3f97293600e8dc99e8e.js?meteor_js_resource=true:9
WebSocket connection to 'wss://myproject.herokuapp.com/graphql'
failed: WebSocket is closed before the connection is established.
and this error :
WebSocket connection to 'wss://myproject.herokuapp.com/graphql'
failed: Error during WebSocket handshake: Unexpected response code:
503
any idea ?
Thanks
So, for magento2 i need to install : PHP Extension intl.
Now after looking up i'm trying to do this but i keep getting errros. I'm on a MAC and i'm using XAMPP, too bad when i run 'sudo pecl install int' i get the following error.
Starting to download intl-3.0.0.tgz (248,200 bytes)

I also tried using 'sudo pecl update-channels' But that gives me the following messages:

What can i do to solve this? I'm using XAMPP with PHP 7.2
I looked at many other similar questions, but none seem to work for me.
I am following this example: http://www.devglan.com/spring-boot/spring-websocket-integration-example-without-stomp
When, I tried this example alone, it is working perfectly. However, when I tried to integrate it with my main project, it seems to be giving the error: WebSocket connection to 'ws://localhost:8080/socket' failed: Error during WebSocket handshake: Unexpected response code: 404
I am just calling index.html directly in my main project.
I am unable to find the source of error.

I upgraded to ruby 1.9.3 this morning, kept the same version of Rails 3.0.8 and installed / updated passenger-3.0.9. Everything seems to run OK when I launch the application, until I try and login (make a database connection), I get a 502 Bad Gateway and the following error message in the console:
[NOTE] You may have encountered a bug in the Ruby interpreter or
extension libraries. Bug reports are welcome. For details:
http://www.ruby-lang.org/bugreport.html
2011/10/31 08:37:22 [error] 6201#0: *6 upstream prematurely closed

Any ideas? Thank you
This has been discussed in the last week on the Passenger mailing list.
Looks like it's still an open bug:
http://code.google.com/p/phusion-passenger/issues/detail?id=714
Only solution I know of is to downgrade to 1.9.2-p290 until it's fixed.
