Can't connect to google cloud engine - google-cloud-platform

Yesterday I connected to my instance successfully but now cloud says following:
ssh_exchange_identification: read: Connection reset by peer
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255].
In ssh.cloud.google.com there is infinite waiting

AWS EC2 Instance keeps disconnecting

Currently, I'm using a Visual Studio Code SSH Plugin to edit my files directly on the EC2 without having to edit it locally and transfer the files. But I've noticed that the EC2 instance has stopped responding after 30 minutes or so and I have to keep rebooting the server in order for it to respond again. The problem is not with the plugin (in terms of connecting to the server) when VSC notifies me saying that the connection as dropped, the same thing occurred to all of my other SSH tools. Is there something I have to do in order for its connection to stay alive?
VSC Plugin: https://code.visualstudio.com/docs/remote/ssh
Error:

Connecting to Could SQL from local machine via proxy

I am following these instructions to deploy a Django app on Google App Engine:
https://cloud.google.com/python/django/appengine
I have got as far as downloading the proxy .exe file (I am on a Windows machine) and connecting to it:
2019/01/08 16:14:08 Listening on 127.0.0.1:3306 for
[INSTANCE-NAME] 2019/01/08 16:14:08
Ready for new connections
When I try and create the Django migrations by running python manage.py createmigrations I see the connection received by the proxy file:
2019/01/08 16:15:06 New connection for
"[INSTANCE-NAME]"
However, after a couple of seconds pause I get this error:
2019/01/08 16:15:28 couldn't connect to
"[INSTANCE-NAME]": dial tcp
35.205.185.133:3307: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
I have tried disabling my local firewall in case this was causing any issues, but the result is the same. I've also checked the username, password and Cloud SQL instance name, they are all correct.
What could be causing this error?

What am i missing? I could not resolve this error. Can someone help me fix this issue?
This error occurs when you run an instance of PopSQL or Node.js and the MySQL server is not running on your local machine.
Try the below steps
Press Windows key and R on your keyboard. This opens the command prompt
Type in services.msc and click ok.
In the services pop up , check for MYSQL57. If its not in the running state, Click on run this service in the left column of the dialog box
Once the service is running connect to the POPSQL from the connections window
The error message you shared indicates your machine could not connect to the instance's IP address on port 3307 (which is used by the proxy). I tested this on my own machine, and it is listening there. This likely indicates a firewall on your machine or your local network that is preventing outbound connections on port 3307. Try and open this in the firewall, and see if you can connect.
You need to whitelist your IP to access Cloud SQL. https://cloud.google.com/sql/docs/mysql/instance-access-control

Spark shuts down after 10 seconds of running

I'm trying to setup clusters in my AWS account (Amazon). I followed this tutorial to set it up. I've ran into some problems regarding ports but I finally got it to work until... it shut down after 10 seconds giving me no more than this error:
16/05/12 12:52:46 INFO client.AppClient$ClientActor: Connecting to master spark://ip-to-my-machine:7077...
16/05/12 12:53:06 INFO client.AppClient$ClientActor: Connecting to master spark://ip-to-my-machine:7077...
16/05/12 12:53:26 ERROR cluster.SparkDeploySchedulerBackend: Application has been killed. Reason: All masters are unresponsive! Giving up.
16/05/12 12:53:26 ERROR scheduler.TaskSchedulerImpl: Exiting due to error from cluster scheduler: All masters are unresponsive! Giving up.
This was the bash I ran to make it work:
bin/spark-shell --master spark://ip-to-my-machine:7077
I opened the TCP port 7077, what seems to be the problem?
