MTProxy error

[lolkda]

Code that causes the issue

with open(f"{config_dir}/login.json", mode="r", encoding="utf-8") as login_file:
login_set = json.load(login_file)

user_id = login_set["user_id"]
bot_token = login_set["bot_token"]
api_id = login_set["api_id"]
api_hash = login_set["api_hash"]
proxy_start = login_set["proxy_start"]
proxy_type = login_set["proxy_type"]
proxy_user = login_set.get("proxy_user")
bot_id = int(login_set["bot_token"].split(":")[0])
connectionType = connection.ConnectionTcpMTProxyRandomizedIntermediate if proxy_type == "MTProxy" else connection.ConnectionTcpFull

if proxy_start and proxy_user and proxy_type != "MTProxy":
proxy = {
"proxy_type": proxy_type,
"addr": login_set["proxy_ip"],
"port": login_set["proxy_port"],
"username": login_set["proxy_user"],
"password": login_set["proxy_password"]
}
elif proxy_start and proxy_type == "MTProxy": ## MTProxy
proxy = (login_set["proxy_ip"], login_set["proxy_port"], login_set["proxy_secret"])
elif proxy_start and proxy_type != "MTProxy":
proxy = (login_set["proxy_type"], login_set["proxy_ip"], login_set["proxy_port"])
else:
proxy = None

bot = TelegramClient(f"{path}/sessions/bot", api_id, api_hash, connection=connectionType, proxy=proxy, connection_retries=None, auto_reconnect=True, timeout=5).start(bot_token=bot_token)

Expected behavior

Normal use of MTPROTO connection

Actual behavior

Connection error using MTPROTO, sock5 and HTTP are normal

Checklist

• The error is in the library's code, and not in my own.
• I have searched for this issue before posting it and there isn't an open duplicate.
• I ran pip install -U https://github.com/LonamiWebs/Telethon/archive/v1.zip and triggered the bug in the latest version.

MTProxies haven't been maintained for a long time. I have no interest currently to learn how they work or to fix them. I also plan to remove direct proxy support in v2. So I will be closing the issue.

You're of course free to search for and use someone else's code that supports these proxies, or roll your own.
