I can call my endpoint using Postman eg, GET : http://localhost:500/foo but when running some native .js code and executing it through npm it cannot resolve the host; is there a reason as to why this happens?
My hosts file contains:
127.0.0.1 localhost
::1 localhost

I am trying to install code-server 3.6.2 on a cloud platform. I have tried both AWS and digitalocean machines but in both systems, I can open code server but it gives an error "WebSocket close with status code 1006".
I have followed the procedure from https://www.digitalocean.com/community/tutorials/how-to-set-up-the-code-server-cloud-ide-platform-on-ubuntu-20-04
code-server uses websocket to connect.Do you use HTTPS?
If so, you should Use wss to forward ws.like this:
// forward websocket (wss -> ws)
httpsServer.on('upgrade', function (req, socket, head) {
proxy.ws(req, socket, head, {
target: 'ws://...',
ws: true
})
})
Usually this and other errors happen when you use code server locally
To solve it you can use the --link parameter that gives you a url with temporary https, or you can also use ngrok
//Option 1
code-server --host 127.0.0.1 --bind-addr 0.0.0.0:9000 --auth password --link
//Option 2
code-server --host 127.0.0.1 --bind-addr 0.0.0.0:9000 --auth password
ngrok http 9000
I have a google appengine project running in localhost. Everything works fine until i go to the 'login' page. When i go there i get the following error:
This site can’t provide a secure connection 127.0.0.1 sent an invalid response.
Try running Windows Network Diagnostics.
ERR_SSL_PROTOCOL_ERROR
the appengine command i use to run the project is dev_appserver.py" --host 127.0.0.1 . This is run pycharm. This only occurs in the 'login' endpoint and no other endpoint.
The console error i get is:
default: "GET /signin HTTP/1.1" 301 -
to connect over HTTPS you need a valid SSL certificate on your server here is you local server as I understand from the message. you can get a certificate for your local server but I don't think it's worth the trouble while working locally. On the other hand when you deploy to Google App Engine, you get SSL certificate automatically and it's managed by Google, that's why your code works without any problem in the deployment.
I like to redirect to a url for sending the confirmation mail, using url_for method
url_for('bun.confirm_email', token=token, mailid=email, _external=True)
Here bun is the name of the blueprint. Since am running the server on the localhost - the url is generated as 127.0.0.1. All my requests to 0.0.0.0 has been proxy forwarded by nginx to localhost, I cannot run the flask server on 0.0.0.0.
Is there a work around where i can get the actual server IP for redirect using blueprint, without actually running the server on 0.0.0.0
I've installed Apache 2 through the Bitmani Django stack and when I access the localhost it works fine, but when I enter the public IP it loads for a bit and then presents that error.
The apache server is running and I have the conf file set to listen on port 80.
What could be going wrong?
I just begun using Flask and tried to run the hello_world example (hello.py)
The point is that I run the server through ssh on a remote machine and I want to browse it from my local machine so I used
app.run(host='0.0.0.0'),
However when I browse on chrome I put let's say http: //RemoteMachineIP:5000/ I got:
Oops! Google Chrome could not connect to RemoteMachineIP:5000
The remote machine has multiple ethernet IP addresses so I tried them (as http: //RemoteMachineIP:5000/) and I am always getting the same error.
I have also tried using app.run(host='LocalMachineIP') in hello.py but I got this error Flask [Errno 99] Cannot assign requested address.
Am I missing something ?
If you can run the server but the browser won't see it, it is a firewall problem.
If you can't assign the ip port, probably there is a PID already using the port, so you should try
lsof -i :5000
Then
kill -9 [PID From the lsof]
