I keep getting the following error while trying to connect o my AWS instance ,I followed the links below and added my local machine's IP to the list of inbound rules in the active security group but still see the problem,can anyone provide assistance on how to debug and overcome this problem?

Possible reasons for timeout when trying to access EC2 instance

I am trying to create a connection to AWS Redshift from the Airflow Web UI, but so far it does not work. I always get the error: ('communication error', ConnectionRefusedError(111, 'Connection refused').
My Redshift is in a subnet of a VPC, but I have allowed public access. In its security group I have furthermore added: 0.0.0.0/0 IPV4 incoming access and my own IP as incoming access allowed.
As The input parameters to the airflow connection template, I use:
As the connection-id: An arbitrary name
host: redshift-clusterxxxxxxxxxxxxxxxxxxxxxxxxxx.redshift.amazonaws.com
The other parameters are also correct.
I have build a little python using redshift_connector to test whether I can connect from there but I am always getting a timeout error.
Has anyone got further ideas on how to solve this issue?
I was no longer able to SSH into a Google Cloud Compute Engine VM instance that previously showed no problems.
The error logs show the following
#type: "type.googleapis.com/google.protobuf.Struct" value: {
conditionNotMet: { userVisibleMessage: "Supplied fingerprint does not
match current metadata fingerprint."
Trying SSH through the console showed
Code: 4003 Reason: failed to connect to backend Please ensure that:
your user account has iap.tunnelInstances.accessViaIAP permission
VM has a firewall rule that allows TCP ingress traffic from the IP range XXX.0/20, port: 22
you can make a proper https connection to the IAP for TCP hostname: https://tunnel.cloudproxy.app You may be able to connect without using
the Cloud Identity-Aware Proxy.
The VM instance logs showed the following
Error watching metadata: Get
http://metadata.google.internal/computeMetadata/v1//?recursive=true&alt=json&wait_for_change=true&timeout_sec=60&last_etag=XXX:
net/http: request canceled (Client.Timeout exceeded while awaiting
headers)
After stopping and restarting the instance I was able to ssh again but I would like to understand the reason for the problem in the first place.
The error message you received indicates that the metadata server's response caused the connection to the Google Compute Engine VM instance to time out. This could be because the server was taking too long to respond or there was a problem with the network. You can try to resolve this issue by either increasing the timeout value by using this doc or waiting for the instance to become healthy using the gcloud compute wait command.
The instance was unable to reach the metadata server, as suggested by the timeout error message. This could be a problem with the instance itself or with the network connection. A firewall or network configuration issue could have prevented the instance from connecting to the metadata server, or an issue with the underlying infrastructure could have rendered the instance temporarily unavailable.
To prevent this issue from happening again, you can increase the timeout value or use the gcloud compute wait command to wait for the instance to become healthy.it is recommended that you regularly update the SSH key used to connect to the instance, and check that the instance can reach the metadata server by making an HTTPS request to the IAP for TCP hostname. Additionally, it is important to ensure that your user account has the "iap.tunnelInstances.accessViaIAP" permission, and that the VM has a firewall rule that allows TCP ingress traffic from the IP range XXX.0/20, port: 22.
If you are using windows vm try troubleshooting steps mentioned in this doc.
Getting error
failed to connect to your instance,
Previously it was running perfectly,
Could you please tell me, why is it not connecting?
my instance is running, occurring this error
failed to connect to your instance, error establishing ssh connection to your instance ec2
Thanks.
Use public and private i-e ppk,pem keys to connect the instance.
Is it possible to post screenshots of error that you are facing? It will give more clear idea. Few suggestions -
If in Security group, for port 22 you have used My ip, try removing it & again give my ip. As home router restarts, new ip is assigned to it.
Check if correct key is used ie pem or ppk
I am trying to connect to AWS RDS database using pgAdmin4, I encounter and error:
Unable to connect to server:
could not connect to server: Connection timed out (0x0000274C/10060)
Is the server running on host "database-1.xxxx.eu-west-2.rds.amazonaws.com" (xx.xxx.xxx.xx) and accepting TCP/IP connections on port 5432?
I have tried to Allow Public Accessibility and InBound Rules from my IP. But I am still getting the error? What seems to be the issue?
I was facing the same error but for the MySQL database in rds. What I did was, I
went to http://checkip.amazonaws.com/ and checked the IP shown. I copied that IP and created a new security group by adding two rules, one is your standard all traffic rule, and the second is the one with custom IP which you just copied. Then went to rds and changed VPC security grp to both default and the one I just created. Do this and try to connect again. It worked for me
For a quick test, try opening your inbound rule like this. If it works, then you know the issue is your IP address in your inbound rule:
Once you set this- can you connect?
I used to be able to connect to my ec2 instance but suddenly I am no longer able to and I do not know why. My security group is the same, allowing ssh from anywhere. I have some information below regarding the errors that I am getting. Please can someone advise?
From FileZilla I am getting:
Error: ssh_init: nodename nor servname provided, or not known
Error: Could not connect to server
From the terminal I am just getting:
ssh: connect to host ec2-xx-xxx-xxx-xxx.eu-west-1.compute.amazonaws.com port 22: Connection refused
i have the same issue i did the following troubleshooting steps and it still gives the same
ssh: connect to host [my public DNS] port 22: Connection refused
i checked the key ".pem" file and its correct on the right directory
no code edits as it used to work fine last night and suddenly this error appeared
i went to the AWS console, selected the instance , and clicked on connect and copied the SSH command to make sure that no typos , and the command is correct
i tried with -v , still same issue.
tried to reboot the instance , no progress
stop then start the instance , no progress
tried to detach the volum and re attach the volum back , no progress
i changed the instance type from t2.micro to t2.small , no progress
checked the security group , port 22 is assigned to all IPs and no problem with the security group at all as it used to work fine
tried from different computers from different networks, same issue
created new instance , i can access the new one but cant ssh to the old one still
my best guess is that the ssh daemon is not enabled but how to access it if i cant ssh to the instance
