I'm trying for several days to connect to a stratum server in nodejs. But I don't get my code working.
I've tried several npm packages but most of them are outdated.
Then I found node-stratum.
This package works fine locally so I expected that it works also with a remote server.
After I changed to host and port to pool.minexmr.com with port number 4444
I got this error message
Oops error: Error: Stratum request without method or result field

I used to code in the example/client
My full code is here codepile
I also tried to change the host to miningpoolhub but there I got no error and it stops by the console.log('Sent!') so I figured out that I better stick with pool.minexmr.com
In the codepile I also added the other logs from the terminal
Okay, finally I got the answer.
Monero stratum has a different payload than Bitcoin
With Wireshark I filtered the payload out en changed the client code van node-stratum.
I changed the node-stratum core code a bit too.

I'm trying to setup a Node.js Websocket server over at my webhost (Namecheap). However, I am getting this error:
events.js:292
throw er; // Unhandled 'error' event

The code for the client and server came from here:
https://github.com/websockets/ws#Simple server
https://github.com/websockets/ws#sending-and-receiving-text-data
with ws://www.host.com/path changed to ws://<mydomainname>/<dir1>/<dir2>
Both client and server code runs properly when run locally. Http related code runs properly when used on my webhost. I am trying to get the client code to run locally and connect via websockets to my server hosted at Namecheap.
I suspect something related to the server is preventing connection. I'd ask support but I doubt if they can resolve this. Maybe there's a locked feature or something? Is there something else I could have missed?
Websockets cannot work on Namecheap's hosted servers. Their incoming ports are blocked and cannot be opened for security reasons per their customer's support.

I am following this tutorial to install a Rocket.chat server in CentOS:
https://hostpresto.com/community/tutorials/how-to-install-rocket-chat-server-on-centos-7/
I am new to mongodb and node.js so I am not very familiar with how all this works
At the moment I am looking for something simple that just works
When I reach the step where it says to execute
node main.js
I get the following error:
[username#localhost Rocket.chat]$ node main.js
/opt/Rocket.chat/programs/server/node_modules/fibers/future.js:313
throw(ex);
^

errmsg: 'not master and slaveOk=false',

[Symbol(mongoErrorContextSymbol)]: {}
}
The tutorial says I should be able to see the Rocket.chat web interface if I go to https://yourdomain.com:3000 but I get an unable to connect page, which I suppose is due to the error above
The tutorial also says node main.js is to check if MongoDB is running or not. I can see that MongoDb service is running by executing
systemctl status mongod
so this error seems to be caused by something else.
How do I find out what is causing this error? Or are there any mistakes in this tutorial? I have found other tutorials regarding installing Rocket.chat in CentOS but most of them use nginx as hte web server while I need to use Apache.
My node.js server file which is hosted on a server is used by my various applications like mobile apps and desktop app.
At some time my server file which is run through forever command crashes and my whole front end system goes down. Why does the server file crash?

If you are using browserSync library then you can check this link
rollback the browserSync version to ^2.6.4 and it works
or try updating your socket.io package as per this link
Please check if your issue is fixed with the latest release
Usually when I start my web application, the browser will open https://localhost:44305
But I want to reach the site from my phone. I've tried changing the applicationhost configfile, firewall inbound rules and all that. But then I found this little thing iisexpress-github
I type this in my console: iisexpress-proxy https://localhost:44305 to 3005
Which results in this line: Proxying https://localhost:44305 to network interfaces:
Ethernet: 192.168.10.41:3005
Listening... [press Control-C to exit]
After following instructions, the browser gives following error: 'Aw snap! Something went wrong. Check your console to see the error.'
And then I look at my console which says the following:
Error: unable to verify the first certificate
at Error (native)

at emitNone (events.js:67:13)
at TLSSocket.emit (events.js:166:7)

Usually my site is https, but this seems only to proxy to normal http.
What to do?
I have my MongoDB server running on localhost:27017, and while I can usually run my Node.js app fine, when I disconnect from the internet Mongoose throws the error
Error: failed to connect to [localhost:27017]
Note that I can still connect to the MongoDB server from the Mongo shell client. Also, if I start up my app first and then lose internet connection, my app can access the database fine offline. So why can't it start up without internet?
EDIT: here is the error in full
events.js:85
throw er; // Unhandled 'error' event
^

Edit: wording
Use 127.0.0.1 instead of localhost. By turning off your wifi interface the OS is no longer able to resolve localhost.
Consider node-offline-localhost.
Add the following before the breaking code:
require('node-offline-localhost').always();
And it just works (hopefully), at least until RFC 3493 gets fixed.
Full disclosure: I authored this package to streamline https in my dev environment when offline.
