Connect Android Device over Proxy Server via SSH and VNC

I try to use SSH on Android the first time, i had read a lot about it but i cant find much, only from Android to Computer. Maybe someone can help me here:)
I have coded an APK for my own Android Device wheres create an SSH Connection over my PHP Script using Proxy Server.
I use an Debian VPS as Proxy Server. With this IP, the Android creates an Proxy.
Now i use this Comment:
ssh -N -L 34836:127.0.0.1:34836 newgenerateduser#23.106.XXX.XX
Port is generated also random every time i create an new proxy over PHP Script.
I use now an Virtual Machine with Ubuntu and enter the Comment in my Terminal with the Passwort after asking.
I start my VNC Client and want get remote Control over my Android device using VNC or SSH with this IP and Port:
127.0.0.1:34836
I got this Message:
lxs#linux-virtual-machine:~$ ssh -N -L 34836:127.0.0.1:34836 newgenerateduser#23.106.XXX.XX
newgenerateduser#23.106.XXX.XX's password:
channel 2: open failed: connect failed: Connection refused
I also tried using localhost instead of IP.
There are special requirements for the Proxy Server? Or just Port blocking on it?
Thanks for your help!

I'm trying to access to my localhost server from my Android Emulator and i'm getting an ECONNREFUSED error

I try to get into the localhost server from android simulator and I can not. What should I do to get in?

Access docker localhost API from Android Emulator

I'm attempting to test my local dockerised API against a staging version of my app.
I don't have access to the repository to build the App myself so I'm relying on changing the IP address within the emulator to point at my local machine and that's where I'm failing.
I've set it to 10.0.2.2 as per the emulator documentation, and when I ping the staging url from the ADB shell (ping mystagingsite.com) it responds data from 10.0.2.2 . But from within the app, the response is always empty. I've tried 127.0.0.1 which obviously won't work, and I've tried my network IP address.
Is what I'm trying to do possible? If it is, what is the right IP address to put in the /etc/hosts file of the emulator and how do I find that address?

Access localhost on laravel valet from Android emulator

I'm using laravel valet to serve an API on a Mac. How can you access it from an Android emulator

As the Android Emulator is different computer than your Mac, you should use the IP address of the Mac (or its name if it is resolved on your network) instead of localhost.
For example if your Mac has IP address 192.168.1.10, then use this address.

Edit the /etc/hosts file on your Android Emulator following the instructions in this SO answer.
Add the following to this file:
myapp.test 10.0.2.2
This will route requests made to myapp.test to 10.0.2.2, which is a static IP address that an AVD uses instead of localhost to access the host.

Access localhost, Mac Android Studio Emulator

I'm running a local http server on port 3000 and i'd like to access that server using an Android emulator. I've tried the following in the browser:
localhost:3000 //
127.0.0.1:3000 // of course I gave my local ip a try
10.0.3.2:3000 // I think this is a genymotion ip?
10.0.2.2:3000 // The most prevailing suggestion was to use this ip
With each of these i'm given this error:
Interestingly when accessing the same in chrome on my desktop:
localhost:3000 // works
127.0.0.1:3000 // doesn't work
Perhaps this is connected? I'm not sure why 127.0.0.1:3000 doesn't work, but that might be a different hurdle altogether.
My /etc/hosts file:
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
I've already tried reloading (& disabling) my firewall and proxies.
The emulator i'm using is:
Mac, Android Studio 1.5.1
Emulator : Nexus 5 - API 21, Android 5.0 x86

Use following Service
https://ngrok.com/
It will give you a tunnel to localhost and give you a URL which you can use from anywhere in the world ;)
