When trying to connect to my google cloud RDP i receive an error saying that my RDP is offline when it is not. At first I thought the error was on my side, but after trying with another RDP it worked fine, any ideas?
You should first check that port 3389 is open on the GCE firewall. If not, run a command like this to create the rule $ gcloud compute firewall-rules create rdp --allow tcp:3389 --source-ranges 0.0.0.0/0 . More info is available here.
Here is a document to troubleshoot RDP issues, you can try these steps. Also you can connect to the instance using a serial console.

I was able to login via ssh normally but it just stopped working.
I tried to stop and start instance but it doesn't help. Could anybody help?
You could check your Firewall Rules in GCP console and if it is not created you can create the rule and with port number 22
$ gcloud compute firewall-rules create default-allow-ssh --allow tcp:22
After try to connect to SSH...
I am getting the following disconnection issues in the GCP Jupiter notebook.
error code: 4010
and
error code: 1006
Can you please suggest some solution?
As part of the IAP configuration steps, you should create a firewall rule that allows ingress traffic to the SSH port from the IAP address range:
GCP Console => VPC network => Firewall rules => Create Firewall Rule
Name: allow-ingress-from-iap
Direction of traffic: Ingress
Target: All instances in the network
Source filter: IP ranges
Source IP ranges: 35.235.240.0/20
Protocols and ports: select TCP and enter 22 to allow SSH
Identity-Aware Proxy > Doc > Setting up IAP for Compute Engine
The error 1006 appears in the GCP Console UI after 1 hour of inactivity of the SSH session via IAP with VMs with Internal IP only, and this is a session timeout on the Google side.
As #mebius99 has mentioned, IAP (Identity-Aware Proxy) requests come from the IP address range 35.235.240.0/20.
Your network firewall must allow these requests to be able to SSH through IAP.
One way to do that (create a firewall-rule) is to run gcloud compute firewall-rules create command.
To do that, first open the cloud shell on the Google cloud console,
Then once the cloud shell opens up, run the following:
gcloud compute firewall-rules create ssh-ingress-from-iap --allow=tcp:22 --source-ranges 35.235.240.0/20 --network [network-name]
Replace [network-name] with your network name (the default VPC network is named: default)
If the above solution doesn't work (or have a similar firewall rule in place already), consider checking the network tags (on the firewall-rules and the VM). It maybe the case that your firewall-rule is allowing the requests to only certain instances that has some tags and the instance you're trying to SSH into doesn't.
For me the error 1006 was related to system Time. I had changed the system time manually to another time zone. SSH worked when system time was sy
Create a firewall for port 22 and add this IP 35.235.240.0/20
attach it to all VM so you will able to establish connection
i´m using ubuntu 18.04 lts in google compute engine and glassfish server running perfectly as seen in the following image:
already configure a static ip to the gcp vm:
and i remove the S so I can access my server
and i also add port 8080 to be able to connect and nothing keeps throwing me error
already try like this :http://34.94.96.242:8080
and this: http://34.94.96.242:4848
And i still don't have access
Did you try reaching your glassfish server inside the Compute Engine?, I mean using for example:
curl localhost:[PORT]
in the terminal and see the output, if OK, your installation is OK and probably there is a firewall rule missing, so you have to create it with the specific port.
For example for enabling traffic in port 22 for using SSH, you need to execute the following command in cloud shell:
gcloud compute firewall-rules create default-allow-ssh --allow tcp:22
or for opening port 8080
gcloud compute firewall-rules create default-allow-glassfish --allow tcp:808
Take a look at this documentation about how to set up firewall rules in GCP step-by-step.
I was using digitalocean and want to try out gcp compute instance. I created an ubuntu instance, did cat ~/.ssh/id_rsa.pub in my terminal and added onto the instance. Then I tried ssh james#external ip in my terminal (I'm using mac) but it just hang there.. then a min later, I got Connection refused error. What's wrong?
There are numerous possible reasons for this, but mostly likely you're missing a firewall rule to allow connections from the outside:
gcloud compute firewall-rules create default-allow-ssh --allow tcp:22
If this doesn't help, check out the Troubleshooting SSH article in the GCP docs.
First check your network can communicate to compute engine via simple ping command.
ping <GCE external IP>
or
telnet <GCE external IP> 22
If you getting request timed out then most probably firewall issue. go to cloud console and create/update firewall rule under VPC section. search tcp:22 in firewalls section and edit/create firewall rule (add your IP ranges into source IP range section) for ssh connection.

I logged to my ssh in google cloud Linux Machine by mistake i changed firewall rule and i lost ssh connection. now i am not able login to ssh(22), Is there any way to recover that ?
I know I can take shanpshots of my machine and create new instances using that snapshot. but is there anyway to get again ssh login in same machine or i have to delete it.
Try connecting to the instance via the serial console: https://cloud.google.com/compute/docs/instances/interacting-with-serial-console. From there you should be able to repair the firewall rules.
pjhsea I tried your steps and it is connecting to serial port but it asks passphrase. I was not sure where I have given this passphrase. If you try to access serial port on gcloud console then it always asks for passphrase.
So I tried below steps and I was able to connect to serial port to change firewall setting on my ubuntu VM.
Goto Compute Engine -> VM Instances fro left side menu.
Click on name of the VM you are facing issue connecting using SSH.
It will open VM Instance details page.
On details tab under VM name there will be two dropdown for remote access.
SSH and Connect to serial console.
Click on serial console and select serial port 1(console)
This connect to serial console without any passphrase and I was able to change my firewall rules using below command.
ufw allow 22
Now you should be able to connect using SSH.
