Python 3.11.1. Getting error Failed to establish a new connection: [Errno -5] No address associated with hostname

I am using zeep 4.2.1 library to consume web services (RFC) from SAP. The API's are working in local server and getting the necessary response. However the API is not working in development environment (docker container).
Getting error message as
HTTPConnectionPool(host=' ', port=): Max retries exceeded with url. (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7ffa989589b0>: Failed to establish a new connection: [Errno -5] No address associated with hostname',))
After doing telnet from development environment response received, it gets connected but after sometime (1 min approx) this error is raised and connection is closed:
408 "Request Time Out" Application Server Error - Traffic control Violation
Note: I have removed hostname from error message but hostname and port are correct. HTTPConnectionPool(host=' ', port=)
Kindly help me does any additional setting required for SAP RFC in docker container

Requests - Python - Failed to establish a new connection: [Errno 111] Connection refused

I have a server running in Ubuntu OS, and I am using Python for getting to learn.
I started an app which I installed, When I opened the app in browser the page is not secure, like this -
I am getting some data from this page using python -
from urllib3.exceptions import InsecureRequestWarning
import requests
requests.urllib3.disable_warnings(category=InsecureRequestWarning)
req = requests.get(url='https://127.0.0.1:7001', verify=False)
This shows an error -
requests.exceptions.ConnectionError: HTTPSConnectionPool(host='127.0.0.1', port=7001): Max retries exceeded with url: / (Caused by
NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7fc2ae5f94f0>: Failed to establish a new connection: [Errno 111] Connection refused'))
When I print the variable req to check the status, but python shows the variable is not defined
How to solve this, thanks

HTTPSConnectionPool(host='127.0.0.1', port=443)
443 is the default port for HTTPS.
You're probably (we can't see how you've defined url, but that's my best guess) trying https://127.0.0.1/..., not https://127.0.0.1:7001/... – fix that in your code.

Use Influxdb client in python - Error : 'InfluxDBClient' object has no attribute 'create_database'/' get_list_database '

I just started using the influxdb client in python. I'm probably doing something wrong but I can't figure it out yet.
from influxdb import InfluxDBClient, DataFrameClient
client=InfluxDBClient(host="localhost",port="8086", username='root')
client.create_database("TEST")
I get the following errors:
ConnectionError: HTTPConnectionPool(host='localhost', port=8086): Max retries exceeded with url: /query?q=CREATE+DATABASE+%22TEST%22 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x0000013E5DD0A8C8>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))
Could you please tell me what I'm doing wrong ? Also is there a command line that I can use to know what's my token/url or what's the token/url of a remote host I would like to access.
Thanks

you are making a mistake while importing.
InfluxDBClient should be imported from influxdb.
like:
from influxdb import InfluxDBClient
also, constructor InfluxDBClient() takes no argument named url and token.
as per the doc, the constructor is:
InfluxDBClient(host='mydomain.com', port=8086, username='myuser', password='mypass', ssl=True, verify_ssl=True)
so your code should be like this:
from influxdb import InfluxDBClient, DataFrameClient
client=InfluxDBClient(host="localhost",port="8086", username='root')
client.create_database("TEST")
client.get_list_database()

how to go to a specific path of host using Python Requests?

I have this host: http://retsau.torontomls.net:7890/and I want to access http://retsau.torontomls.net:7890/rets-treb3pv/server/login, how can I accomplish this using Python Requests? All my attempts till now have failed.
I also followed the solution here - Python Requests - Use navigate site by servers IP and came up with this -
response = requests.get(http://206.152.41.279/rets-treb3pv/server/login, headers={'Host': retsau.torontomls.net})
but that resulted in this error:
requests.exceptions.ConnectionError: HTTPConnectionPool(host='206.152.41.279', port=80): Max retries exceeded with url: /rets-treb3pv/server/login (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x10a4f6d84>: Failed to establish a new connection: [Errno 60] Operation timed out',))
Funny thing is everything seems to work perfectly fine on Postman, I am able to access all sorts of URLs on that server, from logging in to searching for something.

You left out the port number (7890) from the URL to your get call:
response = requests.get('http://206.152.41.279:7890/rets-treb3pv/server/login', headers={'Host': 'retsau.torontomls.net'})
# ^^^^ Add this
Also, unless you actually have a specific reason for accessing the site by IP address, it would make more sense to put the FQDN in the URL rather than the Host header:
response = requests.get('http://retsau.torontomls.net:7890/rets-treb3pv/server/login')

Python soap client - connection having issue

I am using Python soap API client Zeep and here is the code that I have written:
from zeep import Client
def myapi(request):
client = Client("https://siteURL.asmx?wsdl")
key = client.service.LogOnUser('myusername', 'mypassord')
print(key)
it is giving me an error as: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
While I am trying below command the URL works well and shows all the services it has
python -mzeep https://siteURL.asmx?wsdl
Please help to understand what is the reason above code is not working.
PS: I couldn't share site URL which I am trying to connect to.
Additional Info: The site/page is accessible only through intranet and I am testing locally from intranet itself.
Traceback error:
Exception Type: ConnectionError at /music/mypersonalapi/
Exception Value: HTTPSConnectionPool(host='URL I have hidden', port=81):
Max retries exceeded with url: /ABC/XYZ/Logon.asmx
(Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x0546E770>:
Failed to establish a new connection:
[WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond',))
Please note: I have removed URL and Host information from my traceback due to confidentiality

What this does:
python -mzeep https://site/url.asmx?wsdl
is:
c = Client("https://site/url.asmx?wsdl")
c.wsdl.dump()
both alternatives are using port 443 since that is the default https port.
From your traceback we see
Exception Value: HTTPSConnectionPool(host='URL I have hidden', port=81):
which would have been similar to
python -mzeep https://site:81/url.asmx?wsdl
I.e. the command line and your code are not connecting to the same address (also note that port values less than 1024 requires system level permissions to use -- in case you're writing/controlling the service too).
The last line does say "..failed because the connected party did not properly respond after a period of time..", but that is not the underlying reason. In line 3 you can read
Max retries exceeded with url: /ABC/XYZ/Logon.asmx
in other words, you've tried (and failed) to log on too many times and the server is probably doubling the time it uses to respond every time you try (a well known mitigation strategy for "things" that fail to login multiple times -- i.e. look like an attack). The extended delay is most likely causing the error message you see at the bottom.
You'll need to wait a while, or reset your account for the service, and if the service is yours then perhaps turn off this feature during development?

Maybe this can help. I had the same connexion problem (Max retries exceeded...). I solved it by increasing the transport timeout.
client = Client(wsdl=wsdl, transport=Transport(session=session, timeout=120))
