Python/Pyrogram on Mac Server Suddenly Turning up Error 61 Connection Refused

I have a Pyrogram app that has been running for ages with no problems from a server running MacOS. A few days ago, the code suddenly hung up and refuses to work. As soon as I attempt to start the Pyrogram Client(), I immediately get "Err 61 Connection Refused"/"network issues" errors. I have confirmed that my Telegram API account is totally fine. The next assumption was that it was an IP ban issue, but I can't even get the Client to open a socket to an http proxy. Pyrogram documentation has nothing about an Error 61, and now I'm thinking that the problem isn't with Pyrogram but rather with a core Python library (corrupted?).
I have seen references on Stackoverflow to folks running into analogous problems with other Python api/web applications but not randomly after a year of normal operation. Some of them were able to resolve the issue by switching references to "localhost" to "127.0.0.1", but I have no idea where that would be located within the Pyrogram library, nor why that would suddenly be a problem out of the blue with no code or server changes.
Help! ;) Thanks!!

If anyone else runs into this problem, I was able to eventually resolve this by using pip3 to reinstall/upgrade Pyrogram. I still don't know the exact underlying cause, and at this point, I can only assume that either my copy of Pyrogram got corrupted somehow, or else there were changes to Telegram that broke a slightly older version of Pyrogram (I had 1.7.1 installed previously and pip upgraded it to 2.0.35).
pip3 install pyrogram --upgrade

Trying to get AIOKafka to work with self-signed cert (Python)

I've been banging my head against my keyboard for a day now, so I'm giving up and asking for help.
I've got a working consumer using confluence kafka, but I need to make it run as a coroutine so I can get things working with FastAPI. I really wanted to try out AIOKafka for this, but for the life of me, I can't get it to work with a self-signed certificate (this is in our dev env).
Here is the working config for my confluence kafka consumer:
conf = {
"bootstrap.servers": "10.142.252.214:9093",
"group.id": "myConsumerID",
"security.protocol": "SASL_SSL",
"sasl.username": kafkaUser,
"sasl.password": kafkaPass,
"sasl.mechanisms": "PLAIN",
"enable.ssl.certificate.verification": "False",
"on_commit": commit_completed,
"heartbeat.interval.ms": "1000",
"socket.connection.setup.timeout.ms": "10000",
"auto.offset.reset": "earliest"
}
Here is the code I'm trying to use for AIOKafka
async def consume():
cert = "../foo/cert/certificate.pem"
key = "../foo/cert/key.pem"
context2 = ssl.create_default_context()
context2.load_cert_chain(certfile=cert, keyfile=key)
context2.check_hostname = False
context2.verify_mode = CERT_NONE
#context2.ssl_cafile="../foo/cert/CARoot.pem"
context2.ssl_certfile = "cert.pem"
context2.ssl_keyfile = "key.pem"
context2.ssl_password = kafkaKey
context2.ssl_keystore_type = "PEM"
consumer = AIOKafkaConsumer(
'TopicA', 'TopicB',
bootstrap_servers="10.142.252.214:9093",
group_id="myConsumerGroup",
sasl_plain_username="kafkaUser",
sasl_plain_password="kafkaPass",
sasl_mechanism="PLAIN",
security_protocol="SASL_SSL",
ssl_context=context2)
await consumer.start()
try:
# Consume messages
async for msg in consumer:
print("consumed: ", msg.topic, msg.partition, msg.offset,
msg.key, msg.value, msg.timestamp)
finally:
# Will leave consumer group; perform autocommit if enabled.
await consumer.stop()
When I try to run this, I just get the most cryptic errors ever and I can't make any sense on where to start trying to figure out what's wrong.

python connecting to ble device with passkey using bleak

I'm trying to connect to a ble device with bleak that uses a passkey.
async def connect(self, address):
print("Connecting to device...")
async with BleakClient(address) as client:
response = await client.connect()
print(response)
i'm using above code. The device displays the passkey to enter and windows displays the add a device message to input the code, but i get a timeout error from asyncio and never recieve the response to python.
Traceback (most recent call last):
File "C:\Users\halmelam\PycharmProjects\read_passcode\main.py", line 137, in <module>

How do I get the response and how can i send the passkey via python?

python telethon ConnectionError: Connection to Telegram failed 5 time(s)

I'm trying to get every new message sent in a channel with python and then use the data to do some further processing. This is my code:
api_id = *******
api_hash = '**********************'
client = TelegramClient(
'session_name',
api_id,
api_hash,
)
client.start()
print(client.get_me().stringify())
client.send_message('someone', 'Hello! Talking to you from Telethon')
And this is the error that I get:

ConnectionError: Connection to Telegram failed 5 time(s)
Process finished with exit code 1
Telegram is blocked by my country. So I use Lantern to have access to it and I can access web.telegram.com. I also tried using a mtproxy but got the same error.

I don't know which part of my code was wrong, but as I saw many people had the same problem, I decided to post my solution.
I could get telethon work very well with help of this article.
And as I said telegram is blocked in my country so I could use MTProxy with help of telethon documentation at this part: 2.2.5 Using MTProto Proxies.

BZPOPMIN and BZPOPMAX(also non-blocking versions ZPOPMIN and ZPOPMAX) are "Available since 5.0.0". You need to upgrade your redis to at least version 5 to use them, since you use version 3.0.54.
You may check download page for available versions and instructions to download them.

download the latest version of Redis from here and try it will work
