I've been searching about this for several days to no avail. I have a python bot ( polling for updates) running OK at home or any public internet. However, when at work behind a firewall, the bot cannot connect to the server. I believe that the application must know the proxy server, user ID and password in order to proceed. But I cannot a find the way or how to include this info in the bot application. Below is the error message:
2017-03-13 07:13:44,233 - telegram.ext.updater - ERROR - Error
while getting Updates: urllib3 HTTPError HTTPSConnectionPool
(host='api.telegram.org', port=443):Max retries exceeded with

Failed to establish a new connection: [Errno 10061] No connection
could be made because the target machine actively refused it',))
/getUpdates (Caused by NewConnectionError ('
Other thing: The Telegram messenger application runs OK behind this same firewall without any info on the proxy server. So it can connect to the server with no problem. I mention this because another cause could be my company uses websense or something like that to block the telegram server , but it is not the case as the messenger application do work OK.
Thanks a million in advance for any hint.
UPDATE JULY 26th, 2017: The solution was as suggested by Sudheesh. The environmental variables https_proxy needs to be set. At the time of this answer it seems to be I've entered the wrong proxy server or in the wrong way. looking around internet , I've noticed the way to set this is (in windows) is:
set https_proxy=http://proxy_url
Notice the right side of the equal show http ( not https)
Thanks to Sudheesh again!

I am trying to connect to my Exasol SaaS database, I tried via these tools(TALEND, DBVISUALIZER, POWERBI) and via python but I cannot connect and I keep getting the same error.
I saw another post on Exasol community https://community.exasol.com/t5/discussion-forum/exaconnectionfailederror/m-p/8049#M1855 of this type of error but it doesn't explain exactly what was done to fix the error. I tried via the ODBC Data Source administrator(64-bit) too but still the same error. Maybe its an connection issue with my pc self but I'm not sure or maybe I am just inserting wrong values I don't know.
Oh the values I inserted are the recommended ones from what Exasol docs states and I have removed anything about proxy or vpn.
I put my errors under. I tried via different devices and I get the same error I really don't know what I can do any more, so any help will be greatly appreciated.
Note: I am using the Exasol SaaS database and I am currently on the trial mode so I am not sure if this is limiting me.
**Errors: **

My applications versions:

Python: python 3.8.10 -> pyexasol : 0.25.1
The error means that the client is not able to reach the host for some reason. Try the following:
Make sure the database is still online (they auto-shutdown after 2 hours if there is no activity by default)
Check that the IP Address of the host you are connecting with is added to the allow list in the SaaS UI. (see the docs)
Check if your host is able to reach the host and port specified in the SaaS UI (for example using telnet on port 8563). Maybe some firewall is preventing access to the database?
So I did more digging. actually I have no idea what the issue was.
Talend:
I made a connection via JDBC in Talend with the help of exasol-support. The DBType Exasol in talend doesn't work for some reason, its not known if it's talend side or Exasol side, maybe this will be updated in the future. Just remember in the jdbc url type this: "jdbc:exa:yourconnectionstring", don't forget the "exa".
PowerBI:
I tried the connection string with fingerprint method that worked for me. Just put the fingerprint with the connection string and it should connect.

DBvisualizer:
I had a wrong in connection string.
Python:
I had a wrong in connection string.
Hopefully this helps someone.
I am trying to run a GET request for a Github url. Unfortunately, I always get an error message.
I tried it for several different websites and it works, just not for github.
I am trying to do it with Jupyter Notebooks in Python, if that is important.
Here is the Error message:
ConnectionError: HTTPSConnectionPool(host='raw.githubusercontent.com', port=443): Max retries exceeded with url: /jana-hoh/gdp/main/DP_LIVE_22102021141534889.csv (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f7a1c285d60>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution'))
An error message that includes Temporary failure in name resolution indicates that the system's DNS server is unable to convert domain names into their corresponding IP address. Some of the causes are:
Your DNS configuration is correct, but the server is unable to respond to DNS requests at the moment
Firewall rules
No internet connectivity
Most of the times I've encountered this error stemmed from being disconnected to the internet. However, if your internet is working properly, you can try to add another DNS server in /etc/resolv.conf. For example, you can add cloudflare's:
nameserver 1.1.1.1
I registered my own salesforce developer login.
I am able to connect to this from my home computer and my work computer via the salesforce login url.
I am now writing python code to extract from salesforce. The code is below.
The code runs on my work laptop when I am at home and connected to my ISP.
When running the same code on my work laptop at work, (so now using work ISP), the code fails to connect.
The error I get when I run at work is:
requests.exceptions.ConnectionError: HTTPSConnectionPool(host='login.salesforce.com', port=443): Max retries exceeded with url: /services/Soap/u/40.0 (Caused by NewConnectionError(': 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'))
So expect something going on with firewall and what not.
But am confused. It does not seem right that my work laptop is more "open" to outside when I use my ISP. I would have thought the security / firewall would have been implemented in a layer between work laptop and the ISP. So ISP agnostic. These laptops are meant to be used at home as well. I am not doing anything wrong in that respect.
Python code below.
import unicodecsv
from salesforce_bulk import SalesforceBulk
bulk = SalesforceBulk(password='**', username='**', security_token='**')
job = bulk.create_query_job("Contact", contentType='CSV')
batch = bulk.query(job, "select Id,LastName from Contact")
bulk.close_job(job)
while not bulk.is_batch_done(batch):
sleep(10)
for result in bulk.get_all_results_for_query_batch(batch):
reader = unicodecsv.DictReader(result, encoding='utf-8')
for row in reader:
print(row) # dictionary rows
Oops. Figured it out. Need to add proxies parameter when connecting to salesforce at work. Bit of a revelation. There is a level of security/protection that is missing on a work laptop when it used at home. Did not realise that networks / firewall / security worked in such a way.
I have a django project which is currently being hosted on pythonanywhere that uses the Finding api of the open source project ebaysdk-python. Now on my local machine, the site worked perfectly, however, when I execute the api call I get this error message: HTTPConnectionPool(host='svcs.ebay.com', port=80): Max retries exceeded with url: /services/search/FindingService/v1 (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f6560105150>: Failed to establish a new connection: [Errno 111] Connection refused',)).
Now I have scoured the docs and other related questions, but could not figure out the issue. I have verified that my API keys are correct, and my code to execute the api call is straight from the docs. So that I may be pointed in the correct direction: What is the most likely cause for this error to be raised under these circumstances?
Thank you.
Im using requests to routinely download a webpage and check it for updates, but recently ive been getting these errors :
HTTPConnectionPool(host='somehost', port=someport): Max retries
exceeded with url: someurl (Caused by : [Errno
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)
Now this script has been running for weeks with this issue never coming up. Could it be that the site administrator has started blocking my proxy's IP?
I should add that its not against the TOS of the site to scrape it.
Can anyone help me figure out whats the reason for this?
Thanks
The remote connection timed out.
The host you are trying to connect to is not answering; it is not refusing connections, it is just not responding at all to connection attempts.
Perhaps the host is overloaded or down? It could also be caused by the site blocking your IP address by dropping the packets (a firewall DROP rule instead of a REJECT rule).
You can try to connect to the site from a different IP address; if those connections work fine, but not from the original address, there is a higher likelihood that you are deliberately being blocked.
