How do I format the server?

To delete data from a rented server quickly, you need just reinstall the operating system.

Reinstalling the operating system can be carried out through Invapi control panel - tab Reinstall (see the instructions) or using API methods.

Emails sent from my mail server end up in SPAM folder. Why?

Usually the problem with spam filters is linked to several factors:

  • The recipients can perceive your message (plural) as spam and as such report it to the email servers or their own mail servers.
  • The content of the email looks like spam. The email servers have a number of criteria that filter spam depending on the content of the email. For example, this may be the information regarding some great secret revealing remarkable success, exclamation marks and even the word TEST in the email subject.
  • Technical features — sending a large amount of emails daily, incorrect encoding, only images are being sent, etc.

Attention

All this may lead to IP being blocked by email servers, services, customers, or getting the IP blacklisted.

What can I do?

The actions vary depending on individual situation. These are the general guidelines:

  • Study in detail the signs of spam and check your email activity for the past 2 weeks.
  • Eliminate the reasons for emails ending up in Spam folder by taking the following actions:
    • In dealing with Spam complaints HOSTKEY specialists check the blacklists using one of the most reliable services — Spamhaus. We recommend you to check whether or not your IP has been blacklisted and remove it if necessary.
    • If the block occurs on the side of the email server, contact the support.
    • If emails are not being delivered to your clients or contractors, contact their technical specialists.

Why does CentOS start during the OS reinstallation?

This is the correct installation behavior. Currently, all OSes are installed via CentOS. After the installation is completed, the server will be rebooted into the selected OS during installation.

Do you store passwords for dedicated servers or VPS?

We do not store passwords for our customers' dedicated servers or VPS to ensure their security. We also do not have the ability to log into your servers, and we do not install SSH backdoors for recovery, etc. The only way we can assist in this case is via a root password reset.

Where can I find the server or operating system login and password?

The server login and password are sent only to your email address upon server delivery. You cannot view the server password in the Invapi control panel!

I Forgot My Server Password

We do not store passwords for our clients' servers. If you have forgotten the password to your server, you have several options:

  1. Reset password following this instruction using the server's Native console in Invapi or IP KVM.

  2. Self-reinstallation of the system: following these instructions. It is recommended to store the password in a secure location since after installation it will no longer be displayed on the server card. Upon reinstalling the OS you will receive new credentials.

    Attention

    All data on the server will be deleted upon reinstalling the operating system.

  3. Paid password reset in manual mode by contacting our support team. All data will remain unchanged. You can find the password reset fee on this page.

How to Change the Root Password on a Linux or BSD Server

    ssh root@server_ip
    or through remote server control

  2. Change the password using the corresponding console commands:

    1. Ubuntu, Debian

      • Enter 

        passwd root

      • Enter the new root password twice, pressing Enter each time.

      • Save changes:

        sync

      • Restart the system:

        reboot –f

    2. CentOS, Rocky Linux, Alma Linux, Fedora

How to Change the Password for SSH Connection

To change the password for an SSH connection to your server, you need to change the root password on that server. You can only change the password by directly connecting to the server via SSH, Native Console, or by contacting our technical support. Changing the SSH connection password directly from the Invapi interface is not provided.

My processor on the virtual server is running slower

On all HOSTKEY nodes, centralized QoS (Quality of Service) limits for processor load on virtual servers have been configured. If you notice a decrease in your virtual machine's performance, this may indicate that you have exceeded the permissible CPU usage limits established in the HOSTKEY Terms of Service. In such cases, to ensure stable operation for other clients, temporary restrictions on resource allocation may be imposed. After the processor load decreases, your virtual machines will have their previous quotas restored within 30 minutes.

Can you change the size of a disk or its partitioning through Invapi?

No, it is not possible to change the size of a disk or its partitioning through Invapi. These changes can only be made by directly connecting to the operating system.

Can you change the root password of a server through Invapi?

No, you cannot change the root password of a server (from its operating system) through Invapi. You must connect directly to the operating system to make this change.

Can you update the SSL certificate for the domain name attached to the server via Invapi?

No, you cannot update the certificate attached to the domain name via Invapi. If you installed the software from the marketplace when deploying the server, and you were assigned a domain name, you can update the certificate yourself using the Certbot container following this guide.

The lsblk output on a virtual server (VPS/VDS) shows rota=1, which means I have an HDD, but I should have an SSD/NVME. Where is the mistake?

A: On virtual servers, the lsblk command cannot correctly determine the type of physical storage, so all virtual disks report rota=1. This is not an error.

Can adult content (NSFW) be hosted on your servers?

No, it cannot. Hosting adult content (NSFW) on our servers is prohibited by the Terms and Conditions of Service.

Мой VPS имеет статус Активен, но он недоступен по SSH или я не могу зайти на него через консоль.

My VPS has the status Active, but it is unavailable via SSH or I cannot access it through the console.

The Active status in the control panel refers exclusively to your billing (payment for services). This means that your subscription plan is active and the services are paid for, but this does not guarantee the physical operability of the server itself.

If the server is unavailable, go to the Monitoring tab and check the following parameters:

  • VM parameter: If the status unknown is displayed in this field, it means the hypervisor cannot retrieve data from the virtual machine. In this case, your virtual server is effectively unavailable.
  • Power Check: Click the Status button. There you can see the actual power status of the server: whether it is powered on or off. If you see Failed to check VM power status, then the physical server hosting your VPS is powered off.

A server may be physically unavailable even if the services are paid for ("Active") for the following reasons:

  • Scheduled maintenance on the node.
  • Emergency situation (hardware failure) in the datacenter.
  • The management system (hypervisor) has temporarily lost connection to your virtual machine.

I cannot manage my server and a message "Controls are temporarily locked" pops up

To perform necessary technical maintenance or recovery after an incident, access to your server may be locked on our end. In this case, you can wait for the work to be completed and the server to be unlocked, or clarify the reason by contacting Technical Support.
