I had errors 10060 and 10061  The reason was in my antivirus Eset Nod 32   Try to turn off the Firewall of your antivirus as I did or just delete it for a time to test the program  If everything started to work properly  add that program to the exclusion or switch to another antivirus  Also  try to change the  host  variable to an empty string  host       And add socket AF INET  socket SOCK STREAM to the  s  variable  s   socket socket socket AF INET  socket SOCK STREAM

The solution is to use the same IP and Port number in both client and server   Try  in client to use      TCP IP    write the ip number here       TCP PORT   writ the port number here      s connect  TCP IP  TCP PORT

the short term solution is to use the default iis host and port normally 120 0 0 1 and 80 respectively  However am still looking for a more versatile solution

There is no relationship between error and firewall   first  run server program  then run client program in another shell of python  and it will work

Hint  actively refused sounds like somewhat deeper technical trouble  but        actually  this response  and also specifically errno 10061  is also given  if one calls the bin mongo executable and the mongodb service is simply not running on the target machine  This even applies to local machine instances  all happening on localhost       Always rule out for this trivial possibility first  i e  simply by using the command line client to access your db   See here

I was facing a similar problem when I was calling REST API using python library and what I found that my server was going into sleep mode which was leading to this  As soon as I logged in to the server via Remote Desktop Connection  my API call used to work

instead of localhost of  0 0 0 0   use local network address as host in case of both - the server and the client - code  host    192 168 12 12  port   12345 use this host address when binding and connecting to the socket  server bind  host  port   client connect  host  port   this change solved the issue for me

Using the examples from  https   docs python org 3 2 library socketserver html I determined that I needed to set the HOST port to the machine I had the server program running on    So TCPServer on 192 168 0 1 HOST   TCPServer IP 192 168 0 1 then I had to set the TCPClient side to point to the TCPServer IP  So the TCPClient HOST value   192 168 0 1 - Sorry  that s the best I can describe it

The below changes fixed my problem  I struggled with the same error for a week  I would like to share with you all that the solution is simply host      in the server and the client host   ip of the server

The first  Please make sure your port  12345  is opening and then when you using a different network  You have to use the IP address in LAN  Don t use the  localhost  or  127 0 0 1   The solution here is  In server host    192 168 1 12   Ip address in LAN network  In client host    27 32 123 32    external IP Address  Hope it works for you

if you have remote server installed on you machine  give server py host as  localhost  and the port number  then client side   you have to give local ip- 127 0 0 1 and port number  then its works

This could be because of proxy or firewall  If it s proxy  then you need to specify proxy setting at entry point of your code or project   import os  for proxy  proxy    http   10 XX XX XX 8X8X   your own proxy  http    lt user gt   lt pass gt   lt proxy gt   lt port gt    os environ  http proxy     proxy  os environ  HTTP PROXY     proxy os environ  https proxy     proxy os environ  HTTPS PROXY     proxy  rest of code

10061 is WSAECONNREFUSED   connection refused   which means there was nothing listening at the IP port you tried to connect to   There was a firewall product around the year 2000 that issued refusals instead of ignoring incoming connections to blocked ports  but this was quickly recognised as an information leak to attackers and corrected or withdrawn

When you run the code on windows machine  firewall prompts it to allow network access  allow the network access and it will work  if it does not prompts  go to firewall settings   allow an app through firewall and select your python exe and allow network access
