This helped me:

1)
Go to the file /etc/sysctl.conf
Add these lines to the file, then save and exit the file (:wq)

Code: Select all

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

2)
Go to /etc/ssh/sshd_config
Add this line to the file, then save and exit the file (:wq)

Code: Select all

AddressFamily inet

-----------------------------
and reboot system....

Thanks a lot
This helped me:

1)
Go to the file /etc/sysctl.conf
Add these lines to the file, then save and exit the file (:wq)
CODE: SELECT ALL

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

2)
Go to /etc/ssh/sshd_config
Add this line to the file, then save and exit the file (:wq)
CODE: SELECT ALL

AddressFamily inet

Thanks for the above info.

When encountering error 15 in VestaCP, it can be frustrating to find that the instructions provided in discussions do not help. However, the solution you found offers a potential workaround to address the issue. Let's delve into a detailed explanation of how these steps can help in resolving the error:

Editing /etc/sysctl.conf:
1. The file "/etc/sysctl.conf" is a system configuration file that allows you to modify kernel parameters. By adding the following lines to the file:

Code: Select all

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

you are effectively disabling IPv6 for all network interfaces (net.ipv6.conf.all.disable_ipv6 = 1) and the default network interface (net.ipv6.conf.default.disable_ipv6 = 1)._This step can potentially resolve the error by disabling IPv6, which might be causing compatibility issues or network connectivity problems.

Disabling IPv6 can be beneficial if your server or network infrastructure does not fully support or utilize IPv6. In some cases, IPv6-related conflicts or misconfigurations can lead to errors like error 15._ By making these changes, you are instructing the system to prioritize IPv4 over IPv6, potentially eliminating the source of the error.

After adding the lines, ensure you save the changes to the file. Depending on the text editor you are using, you can typically save the file by using the command :wq.

2. Modifying /etc/ssh/sshd_config:
The file "/etc/ssh/sshd_config" is the configuration file for the SSH (Secure Shell) server. By adding the following line:

Code: Select all

AddressFamily inet

you are specifying that the SSH server should only use IPv4 for communication. This step is relevant if there are compatibility issues with IPv6 or if IPv6 is causing the error you are experiencing.

The "AddressFamily" parameter is set to "inet" to explicitly indicate the use of IPv4._ By making this modification, you are ensuring that the SSH server solely relies on IPv4, thereby bypassing any potential conflicts or complications arising from IPv6.

Once again, remember to save the changes to the file using the appropriate command (:wq in most text editors) after adding the line.

It's important to note that the provided solution is specific to addressing error 15 in VestaCP. This error can be caused by various factors, and these steps provide a potential workaround by disabling IPv6 and ensuring the SSH server exclusively uses IPv4. However, each situation may differ, and it is recommended to consult the VestaCP community or support resources for personalized assistance if the error persists or if you encounter a different error.

Additionally, it's advisable to monitor any changes made to system configuration files and be aware of potential implications. In some cases, disabling IPv6 may have an impact on network functionality, depending on your specific setup and requirements.

By following these steps, you have attempted to resolve error 15 in VestaCP by addressing potential issues related to IPv6.

Please guys, note that vestacp is abandoned and there are huge security issues right now. I'd recommend switching to myvestacp (https://myvestacp.com/) or hestiacp (https://hestiacp.com), both vestacp forks. MyVestaCP sticked more to the original vestacp but with more security and hestiacp focused on more features and security as well.

The Lets Encrypt issue was solved in both of them.

Thanks very much for the above detailed solution I also added this with examples:
Certainly! Here's a detailed example for the solution to address error 15 in VestaCP:

Editing /etc/sysctl.conf:
a. Open the /etc/sysctl.conf file using a text editor. For example, you can use nano:

Code: Select all

sudo nano /etc/sysctl.conf

b. Add the following lines at the end of the file to disable IPv6:

Code: Select all

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

c. Save the changes and exit the text editor. In nano, you can do this by pressing Ctrl + O, then Enter, and finally Ctrl + X to exit.

Here's an example of how the /etc/sysctl.conf file would look after adding the lines:

Code: Select all

# ... other configuration lines ...
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

Modifying /etc/ssh/sshd_config:

a. Open the /etc/ssh/sshd_config file using a text editor:

Code: Select all

sudo nano /etc/ssh/sshd_config

b. Add the following line to the file to specify IPv4 usage for the SSH server:

Code: Select all

AddressFamily inet

c. Save the changes and exit the text editor (in nano, press Ctrl + O, then Enter, and Ctrl + X).

Here's an example of how the /etc/ssh/sshd_config file would look after adding the line:

Code: Select all

# ... other configuration lines ...
AddressFamily inet

After making these changes, it's advisable to restart the relevant services to apply the modifications. For example, you can restart the SSH service using the following command:

Code: Select all

sudo systemctl restart ssh

Please note that these steps assume you have administrative privileges on the server. Modify the commands and paths as necessary based on your specific environment.

Remember to exercise caution when modifying system configuration files, take appropriate backups, and ensure you understand the potential implications. Disabling IPv6 may affect network functionality depending on your setup and requirements.

It's important to highlight that this solution is specific to addressing error 15 in VestaCP, which can be caused by various factors. If the error persists or you encounter a different error, it's recommended to seek personalized assistance from the VestaCP community or support resources.

By following these steps, you've attempted to resolve error 15 in VestaCP by addressing potential IPv6-related issues.
