U need use api login from website, login.php read manual from here Welcome! | OpenTibiaBR (https://docs.opentibiabr.com/) <---

danio4don · Jan 21, 2026

I added a plugin to myaac, but it still doesn't work. I've tried everything already.

When I start the server, the website shows normally that the server is online.

The problem is probably with the login server.

are u using canary "stable version 3.2.1?" or using the developing one? It may be port problem? u should use port 80 if u are logging in on the 14+ protocol not the old 7171

danio4don · Jan 21, 2026

I checked versions 3.2.0 and 3.2.1, both versions are the same. I've already tried everything. I changed ports, server IP to domain and vice versa. Nothing wants to help.

danio4don · Jan 21, 2026

The problem is probably in OTClient, because these errors appear in the client console.

It seems more like an error on your website than on OTC.

Try this login.php, put it in the main myaac folder:

I added this file login.php to the myaac folder on the VPS. But when I go to the website, the file still doesn't work.

The file permissions are also correct. What could be the reason it’s not loading?

You have some error, check apache2/nginx logs.

Or enable dev mode in config.local.php

My AI tool suggested that I should remove this in login.php
require_once 'config.php';
require_once 'config.local.php';

now aelthar.com.pl/login.php shows this

{"errorCode":3,"errorMessage":"Unrecognized event ."}

Login still doesn't work.

Should I enter the domain name or the server IP in it?

The same in the Canary config, should I enter the domain name or the server IP?

You should configure Canary + MyAAC then connect to Canary with OTClient Redemption following this

About | OpenTibiaBR

docs.opentibiabr.com

The default login.php from myaac repo should work:

myaac/login.php at main · slawkens/myaac

Automatic Account Creator (AAC) for Open Tibia Servers written in PHP - slawkens/myaac

github.com

(Thanks Majesty)

I did what you wrote, but it's still the same. I can't connect through OTClient, and the logs in OTClient keep showing the same errors.

^
1) assets from 14.12 ( version ), should be placed in /things/1412/All files
2) Sounds should be placed in /sounds/1412/All files

3) Login method:
HTTP

LUA:

Servers_init = {
    ["http://your-domain-or-ip/login.php"] = {
        ["port"] = 80,
        ["protocol"] = 1412,
        ["httpLogin"] = true
    },
}

HTTPS

LUA:

Servers_init = {
    ["https://your-domain-or-ip/login.php"] = {
        ["port"] = 443,
        ["protocol"] = 1412,
        ["httpLogin"] = false
    },
}

I got this working locally, live and by auto login

My init on Linux: ( Its an IPV4 for Vrital Machine )

LUA:

Servers_init = {
    ["192.168.10.216"] = { -- HTTP traffic
        ["port"] = 80,
        ["protocol"] = 1412,
        ["httpLogin"] = true
    },
}

Everything in OTClient is in its place. It has to be an error in OTClient because even if I don't have the server and login enabled, this error still pops up in the OTClient console. No matter what I enter, the error appears in the console.

I always ran Canary, OTClient, login. And I never had any problems with it. Now it won't connect and there are these errors in OTClient.

Post automatically merged: Jan 22, 2026

Problem solved. I was using the latest client from the repository all the time. Now I used 4.0 + hotfix(1) and logged in normally, and there are no errors in the console.

I've already had this incompatibility problem with the client in Canary.

I use a VPS with Ubuntu. Everything is properly configured. It was the client's problem. I downloaded the stable OTClient 4.0 and everything works.
