Serial validation error on CachyOS Linux

[VKDELAS]

Hello everyone,

I'm having an issue validating my serial on CachyOS (Arch-based Linux). Every time I try to enter MTA, I receive the following error:

"There was a problem validating your serial"

I have already followed the official troubleshooting steps, but the problem still persists.

---

What I have already done:

• Installed and started MTA Server 1.6 directly on my host machine (CachyOS Linux x64), NOT inside a virtual machine.

• Fixed the libtinfo.so.5 dependency by creating a symbolic link to libtinfo.so.6.

• The server starts correctly and connects to the Master Server.

• Connected locally via 127.0.0.1, and the server logs my connection.

• When I try authserial VKDELAS, it says:

  "No serials require authorization"

• Generated an HTTP password using:

   

  authserial VKDELAS httppass

  but the old authorization link returns 404 Not Found, so I couldn't complete the validation process.

---

🖥 System Details:

• OS: CachyOS (Arch-based Linux x64)

• MTA Version: 1.6

• Account Name: VKDELAS

---

Is manual serial authorization still possible?
Or is there a new validation page/process that I should use?

I'm attaching a screenshot of the error message and server console.

Any help would be greatly appreciated.
Thank you!
