Handle connection refused error

[Fedour57]

Hello, I'm trying to handle a connection refused error, if I try to connect to a server that doesn't exist, my app crash.

I've try something like this:

try
{
    var client = net.createConnection({ port: 49500, host: "255.0.0.0",timeout:1000 })
}
catch (error)
{
    console.log(error)
}

and also:

 var client = net.createConnection({ port: 49500, host: "255.0.0.0",timeout:1000 })
 .then(val =>
{
    console.log("connected")
}           
).catch(error => {
    console.log(error)
})

But the App still continue to crash with the Connection Refused Exception

Hello developers, I have just recently used the react-native TCP and I encountered with connection refused error while creating the connection if the server is closed, how I handled it, I used net.connect() method rather than create connection, then error event handle the connection refused error, I am pasting the code here so you can see it, Thank you.
`const client = await net.connect(5000,data[i].ipdata_ip,()=>{
client.write(JSON.stringify({
tableNum: tab,
time: Moment(new Date()).format('MM-DD-YYYY hh:mm:ss A')
}));
client.destroy()

})
client.on('error',(error)=>{
alert(Configuration kitchen error at screen ${data[i].ipdata_ip})
})`
