Azure Instance with linux machine docker timing out on requests

I have a python script in a docker that runs and collects data from an api on a loop.
`for idx, items in enumerate(SearchList):
#get access token
access_token = GetPricingAccTok()
#request id to get results
reqid = RequestIdCompSearch(items, access_token)
#api to get results by doing a while loop appending results together till api returns 100% as completed percentage
Result = GetReqResults(reqid, access_token)
Pricings = GetPricingDict(Result)
filenamepricing = "pricinghistory/CorrectFormat/Pricings_Data_{idn}_{ts}.json".format(
idn = idx,
ts= dt.datetime.now().isoformat()
)
GetAzContainer().upload_blob(
name=filenamepricing,
data=json.dumps(obj= Pricings, indent=4),
blob_type='BlockBlob'
)
`
When i run and test this code locally on my windows machine it works well without an issue and completes the requests
but in the docker on azure container instance it then returns an error showing that the connection has timed out. Not sure what the difference is between the running it locally and in the docker that i then recieve this error.
I have tried addinng this code at the start
import socket
from urllib3.connection import HTTPConnection
HTTPConnection.default_socket_options =(HTTPConnection.default_socket_options + [
(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1) #Enables the feature
,(socket.SOL_TCP, socket.TCP_KEEPIDLE, 45) #Overrides the time when the stack willl start sending KeppAlives after no data received on a Persistent Connection
,(socket.SOL_TCP, socket.TCP_KEEPINTVL, 10) #Defines how often thoe KA will be sent between them
,(socket.SOL_TCP, socket.TCP_KEEPCNT, 60) #How many attemps will your code try if the server goes down before droping the connection.
]
)
but it still times out. showing the below error

Tornado: how to close file object if exception/error in data_received when streaming chunked data to file

I am running Tornado with stream_request_body and saving a file POST request to file on server. In prepare I create the file object and in post I close file object. How do I capture any error/exception in data_received so that I can close the file object properly?

self.file.write(chunk)

self.file.close()
self.write('UPLOADED')

class UploadHandler(...):

def on_connection_close(self):
self.file.close()

Can't continue a program when binance api(connection) error occured

I'm fetching OHLCV data from Binance via Binance api on AWS-EC2.
But sometime(once a couple of days) error "104, 'ECONNRESET'" occur and program stop.
The program written in Python3.7.3 and run on AWS-EC2
The code is following. But this code couldn't continue.
I want to continue the program running when any api or connection error occured.
How should I handle this error ?
while True:
..............
try :
klines = client.get_historical_klines(ticker_symbol, Client.KLINE_INTERVAL_1MINUTE, _from_str, _until_str)
except BinanceAPIException as e:
print(e)
print('Something went wrong. Error occured at %s. Wait for 1 hour.' % (datetime.datetime.now().astimezone(timezone('UTC'))))
sleep(3600)
continue
..............
All error massege are following.

Assuming that you are using python-binance module, most likely the error happens because you are trying to reuse the client after long time (server timeout). You can try to recreate the client first:
...
client = Client(api_key, api_secret)
while True:
...
try :
klines = client.get_historical_klines(ticker_symbol, Client.KLINE_INTERVAL_1MINUTE, _from_str, _until_str)
except BinanceAPIException as e:
print(e)
print('Something went wrong. Error occured at %s. Wait for 1 hour.' % (datetime.datetime.now().astimezone(timezone('UTC'))))
sleep(3600)
client = Client(api_key, api_secret)
continue
...
The reason is because the [Client][2] uses requests Session underneath which imply usage of urllib3's connection pooling. This connection pooling can not be reused after timeout.

Why do i get ConnectionResetError 10054 error?

I am writing a simply python script for vkontakte.com (vk.com). It's main task is to run constantly in background, tracking one exact group chat. When it comes to a new message in chat, script answers back on special keywords. Nothing hard. I am kinda new to python and it's connection architecture. After a random time script fails due ConnectionResetError when it comes to answer back with vk.messages.send() function. Fails completly random - might work for 9 minutes or 20 minutes, most of time fails during message send, but also fails if i leave script working for 20+ minutes time. What do i do now ? I need it to work constantly. Also i want to understand why connection fails.
main loop that tracks new messages is written like this:
for event in longpoll.listen():
if event.type == VkEventType.MESSAGE_NEW and event.to_me and event.text:

eBay Python SDK Trading API Connection Issue

I'm trying to retrieve the Session ID and FetchToken like the following.
import datetime
from ebaysdk.exception import ConnectionError
from ebaysdk.trading import Connection
try:
api = Connection(appid='APP_ID',
devid='DEV_ID',
certid='CERT_ID',
config_file=None)
response = api.execute('GetSessionID') # <<===== I'm executing here to understand the response
# response = api.execute('FetchToken', runame='RUNAME')
# response = api.execute('GetSellerList', runame='RUNAME')
except ConnectionError as e:
print(e)
print(e.response.dict())
But when I execute api.execute('GetSessionID') to test, I have a connection error like this:

The idea is to retrieve the SessionID and reuse it to call FetchToken later and be able to access the other methods from Trading API. But without it working properly I can't do nothing on Trading API.
Thanks in advance.

I know this might be late, but try this in requirements.txt:
