After connecting to VPN I am facing issue with docker-machine create on windows 7. This is the error coming:
This machine has been allocated an IP address, but Docker Machine could not
reach it successfully.
SSH for the machine should still work, but connecting to exposed ports, such as
the Docker daemon port (usually :2376), may not work properly.
You may need to add the route manually, or use another related workaround.
This could be due to a VPN, proxy, or host file configuration issue.
You also might want to clear any VirtualBox host only interfaces you are not using.
Checking connection to Docker...
Error creating machine: Error checking the host: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168
.99.101:2376": dial tcp 192.168.99.101:2376: connectex: No connection could be made because the target machine actively refused it.
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which might stop running containers.
This issue is coming when connecting to vpn. Can anyone please help me with this issue?
Thanks,

I am running a docker container of python server in my computer (MacOS Catalina, the container can connect MySQL and Redis from host computer, the server is running normally, but I can't visit server on host computer), in Linux environment, we need to disable the selinux, firewall and iptables, for example, edit /etc/selinux/config
and type as below
SELINUX=disabled
SELINUXTYPE=targeted
How to disable selinux/iptables in MacOS or how to visit docker server from the Host computer, I already tried to use host.docker.internal instead of 127.0.0.1, but it doesn't work, if I use host.docker.internal in MySQL or Redis config, also failed, I only can use the really IP such as 192.168.1.45 instead of host.docker.internal or 127.0.0.1
I have Jboss running in a docker container. On jboss I have defined a connection to the xa-datasource database as the ip address of my computer and not localhost because I work in Windows 10. Despite the correct ip and port to the database (oracle) I keep getting the connection refused error. I run jboss with the command
docker run -d -p 8080:8080 -p 9990:9990 myjboss
Can anyone help me, or do I need any additional settings in my docker. I will add that I also test alpine and in the container (exec) I can ping my ip address.
Thanks a lot for all the answers. I would like to add that I tested all other solutions contained in similar questions, but unfortunately I did not get the expected results.
If you can ping your host IP, but you can’t connect to the database, granted that the DB is running and the listener is up...
I’d advise you to check the Windows Firewall settings.
Maybe try disabling it to check if you can actually connect to the database, if so, add an Inbound Rule to the firewall to allow connections on port 1521 (or whatever port your listener is running on)
I solved this problem by using not ip/localhost but host.docker.internal as described here -> https://docs.docker.com/docker-for-windows/networking/
I have installed Virtual Box (Version 5.2.0 r118431 (Qt5.6.2)) on Windows 10 and i imported appliance HDP_2.4_virtualbox_v3 (downloaded from here).
I followed the tutorial from here step by step.
The virtual machine is running on the computer from where I am trying to access the Dashboard. I have set up the Host Only Adapter Option on the sandbox so the computer and the virtual machine can communicate
After the CentOs finished booting I am prompt to enter to the ip 127.0.0.1:8888, which is a different address from the tutorial,
and there is no server listening to that address because i get
"127.0.0.1 refused to connect." in the browser.

Run the ipconfig command in your command prompt and identyfy your virtual box's ip under Ethernet adapter VirtualBox Host-Only Network.
Take that ip address and go to your Virtual Box.
Select your appliance and go to Settings->Network->Adapter 1->Port Forwarding.
Replace the Host IP 127.0.0.1 for the port you need 8080, 8888 and so on with the ip of your virtual box that should be sth like 192.168.x.x.
Now start your sandbox, login on it and try to connect in your browser to the new ip set 192.168.x.x:8888.
Use appliance HDP_2.4_virtualbox because in the most recent some linux commands like netstat are considered deprecated and no longer function, which willmake your life harder when trying to debug or identify a networking problem.
If you still encounter issues eith it, reinstall your operating system, reinstall your virtual box and reimport the sandbox, make the changes needed in the Port Forwarding settings and it should be ok.
try to connect using 127.0.0.1 to connect make sure the VM is running make sure there are no errors if there are debug them and at the last straw uninstall the Vm and retry (make sure to make a backup if there are any files)
you can also try to check all the local host ips on your network and try to connect to them
Make sure you set NAT in your VirtualBox network settings:
I am trying to set up docker machine on Windows and this problem has annoyed me for a few days.
I downloaded and installed DockerToolbox-1.9.1a on my Windows, so it came with Virtual Box version 5.0.10. After that I ran this command to create my virtual machine:
docker-machine create --driver virtualbox --engine-insecure-registry docker.pre-prod.ss.local:5000 --virtualbox-hostonly-cidr 192.168.99.100/24 mymachine
Here is what I got:
Waiting for machine to be running, this may take a few minutes...
Machine is running, waiting for SSH to be available... Detecting
operating system of created instance... Detecting the provisioner...

This could be due to a VPN, proxy, or host file configuration issue.

The machine was created successfully. So I ran the docker-machine env command:
docker-machine env --shell=powershell mymachine| Invoke-Expression
and I got:
Error running connection boilerplate: Error checking and/or

Running docker version returned

2015 OS/Arch: windows/amd64 An error occurred trying to connect:

Can someone help to point out the direction to fix this issue? It is really troublesome to set up docker on Windows. Thank you very much.
I use docker 1.9.1 on Windows (7, 8 and even 10), but without docker registry, and without using --virtualbox-hostonly-cidr.
If you are to use that last option, check "Set a specific address ip when i create a docker container", where I mention issue 1709, which uses cidr in .1, not .100 (but getting a .100 ip address as a result):
docker-machine create -d virtualbox --virtualbox-hostonly-cidr "192.168.99.1/24" m99
If there's no other machine with the same cidr (Classless Inter-Domain Routing), the machine should always get the .100 IP upon start.
I am trying to run putty on Windows 7.
I need to run some SSH commands to upgrade Magento. Every time putty gives me this fatal error:
network error: connection refused
I have even tried to use it through winSCP. Note that putty is running fine on my client's side, but for me it's giving me that error every time.
I tried using port 22, 23 and a few others without success. I have also tried with Windows Firewall both enabled and disabled.
Thank you.
Install open-ssh or ssh in target Linux machine solved my problem .
Use below commands:
sudo apt install ssh
sudo systemctl status ssh
sudo systemctl enable ssh
The following are the list of possibilities of this error:
1) Common cause is - Your IP is blocked or not whitelisted in the server which can be done by editing the file at /etc/csf/csf.conf
2) Disable the windows firewall settings and check..
The above two things should work in most of the cases
3) This is very unusual and when the above two options fails it is very difficult to find the solution
In this case the traceroute to the server host or IP works usually but putty fails
port 22 looks normal and working but connection fails and restarting SSH (service ssh restart) also does not work
reboot or restart the server but still fails
Adding IP in firewalls or whitelisting the local IP may not workout
This case generally happens when the server is migrated or new server. IP of the old server might be whitelisted locally, but don't have port 22 open, or some other local filtering is occurring for this new IP but not the old server IP..
In this case you need to change the port to some 522 or 530 some unusual port will help in sorting it out.. The same port you have to use for the SFTP connection also .. where as FTP connections works normally..
or you have to whitelist the IP locally or open the TCP in and out to port 22 if you want to use the port 22..
