Starting Kitematic on Windows 10 gives me this error
Error: connect ETIMEDOUT 198.105.254.24:2375
I'm already running 'default' vm in VirtualBox. The only way to start Kitematic is to hit the 'USE VIRTUALBOX' button.
Why won't Kitematic start unless I click 'USE VIRTUALBOX' button? I've already got VirtualBox running the 'default' vm successfully...
I commented on the docker / kitematic Github issues page and one of the participants told me to simply click USE VIRTUALBOX button to use VirtualBox on Windows since they are in favor of Docker for Windows.

You can turn off Hyper-V in your system, then reboot and click run VirtualBox next time.
I faced the same error. Below solution worked for me:
Deleted the folder C:\Users\{Account_name}\.docker
Clicked on the "Retry setup" button on Kitematic. It re-created C:\Users\{Account_name}\.docker with a new default machine. Error : connect ETIMEDOUT 192.168.xxx.xxx:2376 disappeared but faced new error: C:\Users\{Account_name}\.docker\machine\machines\default\ca.pem does not exist
Copied all certificate files from C:\Users\{Account_name}\.docker\machine\certs to C:\Users\{Account_name}\.docker\machine\machines\default. Then I got error
Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.xxx.xxx:2376"
Regenerated certificates for default machine by running below command on Command Prompt.
docker-machine regenerate-certs default
It showed below output:
Regenerate TLS machine certs? Warning: this is irreversible. (y/n): y
Regenerating TLS certificates
Waiting for SSH to be available...
Detecting the provisioner...
Copying certs to the local machine directory...
Copying certs to the remote machine...
Setting Docker configuration on the remote daemon...
After this, I was able to access default machine through Kitematic GUI. I figured that issue was due to TLS connection and these steps fixed it.

I am using Docker for Desktop with version 20.10.17. Whenever I try to enable Kubernetes v1.24.2 from Docker Desktop and then click on apply and restart, it shows "Kubernetes failed to start". Moreover, when I type kubectl version in cmd, the version for client is shown but for server it displays "Unable to connect to server: EOF". I have tried a number of solutions including purging and resetting from troubleshooting option of docker desktop. I have disabled VPN, firewall but nothing is helping me. Can anyone help me overcome this problem?
Our application is docker based and requires Nat network to be created on the host machine in order to communicate since its a web service. It was working since last 4 months and suddenly stopped working. Checked and found that docker service is stopped. Manually tried restarting the service but it failed to start. Below is the error in the event log:
Error:
fatal: failed to start deamon: Error initializing network controller: Error creating default network: failed during hnsCallRawResponse: hnsCall failed in Win32: There are no more endpoints available from endpoint mapper. (0x6d9)
Tried the below steps:
Deleted the hns.data and restarted the hns service. Then restarted the docker engine service. The issue persists.
Tried running MOFCOMP. Same issue.
Tried removing docker and reinstalling it. Doesn't work.
Tried creating nat network manually. But getting the above mentioned error.
Can someone help here? what needs to be checked or what could be the reason for this issue?
I want to develop code inside a container on a remote Docker host with VS Code, but I cannot connect to Docker on the remote machine via SSH (ECONNREFUSED 127.0.0.1:80).
Following the VS Code instructions to use a SSH tunnel (https://code.visualstudio.com/docs/remote/containers-advanced#_option-2-connect-using-an-ssh-tunnel) I got this error:
"Unable to connect to Docker. Please make sure you have installed
Docker and that it is running. Details: connect ECONNREFUSED
127.0.0.1:80"
I started VS Code (Windows 10), updated the docker.host (File->Preferences) property to:
{
"docker.host":"tcp://localhost:23750"
}
and ran:
ssh -NL localhost:23750:/var/run/docker.sock user#hostname
It looked like established the tunnel successfully. I run Docker on a virtual machine (centOS).
When I opened the Docker view and expanded the Containers node in the explorer I got the above mentioned error. To me it looks like VS Code tries to connect to port 80 but I specified port 23750 in the settings. How can I successfully connect to the remote host?
I found a fix here: https://github.com/microsoft/vscode-docker/issues/580
Remove the prefix tcp:// from the docker.host settings, e.g.:
"docker.host": "localhost:23750"
I know that this question is old but for anyone still looking for options I solved a similar issue on my computer using IPv6.
So in your case:
{
"docker.host":"tcp://[::1]:23750"
}
I configured the host on the environment variable DOCKER_HOST.
I am using windows 10 professional and I have installed docker using DockerToolBox, so I have a docker-machine running in VirtualBox. When trying to configure an interpreter in PyCharm using my docker-machine, I get the following error:
"Cannot connect: java.lang.NullPointerException: uri was not specified"
docker-machine error
When I choose 'TCP socket', I get the following error which is different from above:
"Cannot connect: java.io.IOException: Channel disconnected before any data was received"
TCP socket error
I am sure my docker-machine is running because I can connect to it using terminal tools like MobaXterm or XShell, and I can also connect to MySQL running in my docker-machine.
Replacing tcp:// by https:// in the api url works for me in Webstorm (Windows 8.1).

I have tried thousands of methods, and finally resolved this problem. The solution is running pycharm as administrator. WTF
I have same issue.
You must check Pycharm logs. There is detailed information about error.
In my case Pycharm shows same error "Channel disconnected before any data was received".
But in logs i found that error is caused by:
"ERROR - HttpResponseStreamHandlerFixed - exceptionCaught before first read or disconnect, we may be hanging
io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: No name matching "my_server_hostname" found"
In my case, the problem was that domain name that i connecting to is in not the same as hostname in SSL self signed cert installed in dockerd.
Domain name that you are connecting to must match domain name in SSL cert that dockerd uses.
I have to make hosts record (C:\Windows\System32\drivers\etc\hosts on Windows, and /etc/hosts on Linux) and connect to it.
And "https://" protocol is required :)
PS. You can check SSL cert hostname by opening Chrome browser to the docker API endpoint with https and opening certificate details.
I've just installed docker on my windows 7 machine. When I start Docker QuickStart, I get following error which seems to be while creating the machine:

There is a similar issue in docker/machine/issues/2773.
Try and see if the issue persists when creating a machine yourself instead of using quick-start:
Find where docker-machine.exe has been installed (or copy the latest released one in your %PATH%) and use that, from a regular CMD session:
First test the existing machine:
# find the name of the machine created.
docker-machine ls
docker-machine env --shell cmd <nameOfTheMachine>
docker machine ssh <nameOfTheMachine>
Then try creating a new one:
docker-machine create -d virtualbox <aNewMachine>
docker-machine env --shell cmd <aNewMachine>
docker machine ssh <aNewMachine>
I do not have a solution but found the root cause.
I had installed boot2docker and has been using for months. I had been creating all
my vbox images on the same folder all the while.
One fine day I decided to archive my machines and changed the folder in which I was creating the vbox images. It started giving this wired error. I reverted back my archive and tested again. It started working fine.
The difference I found on both the set up was, in the archived folder it was skipping the ca cert creation step and was directly creating the machine. In the new folder it was creating a cert and then creating the machine. It looks like the server doesn't like the new certs!!!!
