ssh: connect to host ********* port 22: Connection timed out - linux

I have Ubuntu 22.04 newly installed on my laptop. I am trying to connect to a remote server and getting the following error:
ssh: connect to host ********* port 22: Connection timed out
I tried some solutions which include,
ping the IP address
adding the IP address to the firewall using sudo ufw
installing ssh and openssh
However, nothing seems to work. I'd be thankful if someone can help me to solve this problem.

If you can ping the server it can be the following causes:
The server is not answering ssh, sometimes ssh server is not up or it is answering in another port.
There is a firewall blocking your request.
You do not need to install the openssh server in your computer to access a remote hosts and normally outbound connections are allowed by ufw.

Solving the a client side SSH connection error

Essentially I cannot connect to an SSH server anymore. Whenever I try to connect I get the following error:
ssh: connect to host HOSTNAME port 22: Connection refused
Note that I am able to connect from a different machine. Hence, the issue seems to be client side. Furthermore, I also cannot pull/push to git repositories that are cloned via ssh. Again, when pulling I get the following error:
ssh: connect to host github.com port 22: Connection refused
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists
It seems like I somehow nuked my SSH installations/config files. I have reinstalled SSH but this did not fix the problem. Any ideas?
Note that you never "connect" to github.com directly (no interactive shell)
As mentioned here, "Connection refused" means
invalid IP address for github.com (manual entry in /etc/hosts or your resolver)
firewall along the way to github.com which blocks the ssh traffic (eg. local firewall or corporate firewall)
So is the other machine (where you do succeed) on the same network?
Check if the other machine SSH config file was not using ssh.gthub.com port 443 (instead of the default github.com:22, typically blocked in a corporate environment).

Logs to troubleshoot SSH tunneling errors

I am trying to troubleshoot connection errors when using SSH tunneling to connect to a rhel 8 EC2 server. Does anyone know of a log location on RHEL 8 that may contain more information when the connection is refused?
For reference I am using the following command (which works on all my other servers)
ssh -i -L 8745:IPOfServer:8443 ec2-user#IPOfServer
I get the error "open failed: connect failded: Connection refused
I can connect on 8080 but 8443 is refused even though the port is open and the application and firewalld are configured to listen on 8443 and 8080.
Thanks!!

Accessing CRC (OpenShift) on a remote server: "openshift crc ssh: connect to host xxx.xxx.xxx.xxx port 22: Connection refused"

I ask you for help because I was unable to access the OpenShift web console, installed in a VM, from my pc.
I am not an expert on linux, so please excuse me if I make any mistakes in exposing the problem.
I followed these steps:
I accessed the shell of the VM via SSH.
I successfully installed CRC on VM following this guide: https://crc.dev/crc/#installation_gsg.
I added at the end of my computer's etc/hosts file the following line: 127.0.0.1 oauth-openshift.apps-crc.testing console-openshift-console.apps-crc.testing downloads-openshift-console.apps-crc.testing default-route-openshift-image-registry.apps-crc.testing canary-openshift-ingress-canary.apps-crc.testing
I tried to access the web console of Openshift via SSH with this command: ssh -L 443:console-openshift-console.apps-crc.testing:443 myuser#xxx.xx.x.xxx
But I got the following error message: ssh: connect to host xxx.xxx.xxx.xxx port 22: Connection refused.
If it helps, by running the same command with -v flag, I get: debug1: /etc/ssh/ssh_config line 19: include /etc/ssh/ssh_config.d/*.conf matched no files
What could be the problem? Did I do something wrong or did I forget any configuration to do?
Many thanks in advance.

Node Js ssh: connect to host port 22. No route to host

Hi I in an attempt to connect to more than one aws account I did a number of stuff that has led to this error. "ssh: connect to host abc.com port 22: No route to host" I dont know what the problem is or how to solve it.
This kind of issue occurs mostly due to following reasons:
Maybe your device is not properly connected to internet. Check your internet connection and try to load again.
May be config file has incorrect information. Check your config file has correct information. Check your ssh directory and ensure that ssh key exists.

ssh: Connection refused while trying ssh from host (centOS 6.5) to guest server (on oracle virtual box, ubuntu 15)

I have setup ubuntu 15 on oracle virtual box on centOS 6.5 (host), using Bridged Network utility. When I'm login from guest server to host server using ssh, it works fine but if I am trying to login from host server to guest, it throws an error:
ssh: connect to host 10.0.41.143 port 22: Connection refused
FYI,
Host IP: 10.0.61.49
Guest IP: 10.0.41.143
Adding as an answer (copied from my comments on the OPs question) so that others may find the answer more easily. (and Hemant can mark it as correct :) )
Is the ssh daemon running on the guest?
There is a ssh client (the one you use to login from) and a ssh server - the target machine you're trying to login to .. you may have the client on the guest, but not the server (sshd)
Check for firewall. It could be blocking the incoming connection on port 22.
Thanks FreudianSlip,
I had only ssh client on my guest server, but not ssh-server daemon.
Installation of ssh-server, resolved the problem :)
