There could be two main reasons why an instance cannot be properly initialized and got stuck on loading:
Incorrect firewall settings
It is crucial for both your operating system safety and Linked Helper work to have firewall enabled where incoming connections are denied by default (except those you added for special needs, for example, port 22 for SSH connections), especially if you manage the tool on a remote server.
You need to double check that you have the firewall enabled and no one from outside can go through firewall.
Windows
- Click Windows Start menu, type "firewall" and open Windows Defender Firewawll:
- Make sure it is enabled, enable it if it is not:
- Once it is enabled, go to the Advanced settings:
- Go to the Inbound rules, select all rules with "linked-helper.exe" name and delete them:
Ubuntu
- Click Activities, type "Terminal" and open it:
- To check the Firewall status, type the following command below, hit Enter, and provide your user password if needed:
sudo ufw status
- If the firewall is inactive, you need to activate it. But before doing that, you need to whitelist certain ports you might be using for remote connections by executing these commands one by one:
sudo ufw allow ssh
sudo ufw allow 22/tcp
sudo ufw allow 2222/tcp
sudo ufw allow from any to any port 3389 proto tcp - Then enable the firewall using the following command:
sudo ufw enable
macOS
- Open Launchpad:
- Open System Preferences:
- Open Security & Privacy and Navigate to the Firewall tab:
- Click the Lock in the bottom left corner and enter your user password to unlock settings and make changes:2012
- Turn on the Firewall:
Incorrect hosts file setting
The hosts file on your PC (it is used by the operating system to connect host names / domain names with IP addresses) on your PC is missing these lines:
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
In order to fix the problem, you need to add them to the hosts file. Here is how to do that:
macOS
- launch Terminal: click the Launchpad icon
in the Dock, type Terminal in the search field, then click Terminal - Open or quit Terminal on Mac
- type:
sudo nano /private/etc/hosts
- press Enter button, type your admin password and press Enter again:
You will now have the hosts file open in the Nano editor. Use the arrow keys on your keyboard, to navigate and edit the file.
- navigate to the end of the file
- paste these lines:
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
- save the file by pressing Ctrl + O:
- then press Enter button
- exit with Ctrl + X
- restart Linked Helper
Windows
- run Notepad as administrator (confirm that you want to allow the program to make changes to your PC):
- in Notepad, click the File menu, then choose Open...

- 1) navigate to disk C:\ => Windows => System32 => drivers => etc or enter this line into address bar and click enter button:
C:\Windows\System32\drivers\etc - 2) choose type file: All files
- 3) choose hosts file by clicking it
- 4) click Open button
- 1) navigate to disk C:\ => Windows => System32 => drivers => etc or enter this line into address bar and click enter button:
- paste these lines into the opened file:
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
- click the File menu, then Save:

- navigate to the end of the file
- paste these lines:
127.0.0.1 localhost
255.255.255.255 broadcasthost
