@markotoplak Is this a proxy thing?

[markotoplak]

@HarishDawath, how is your internet connection working? Are you perhaps using proxies or a VPN?

If you need a proxy server and it was not automatically detected, go to Orange's settings (on windows under Options) and enter a proxy server manually.

I had the same problem yesterday. For me, updating all packages via conda helped. Perhaps, you have to update your Orange installation?

A proxies hack

Instead of trying to use the following hack, try to set proxies in the settings windows. -- @markotoplak

Orange Data mining --> lib --> site packages -->requests --> adapters.py

1. open the script adapters.py and search for the line where the function “send” is defined :

def send(self, request, stream=False, timeout=None, verify=True, cert=None, proxies=None):

2. add this line: proxies = None just before conn = self.get_connection(request.url, proxies)
like this :
try:
proxies = None
conn = self.get_connection(request.url, proxies)
3. Save

Fixing cachecontrol/msgpacks incompatibilities

There used to be an incompatibility with cachecontrol/msgpack libraries. The bottom should not be useful anymore. If you get problems, try to update cachecontrol or msgpack. If that does not fix them, please report a new bug. -- @markotoplak

Now let’s open another file:
Orange Data mining --> lib --> site packages -->cache control -->serialize.py

in the bottom of the script :

1. find the function _loads_V4 :
def _loads_v4(self, request, data):
try:
#cached = msgpack.loads(data, encoding="utf-8") ( comment this line ) ~~
~~ and change it with this line :
cached = msgpack.loads(data)

2. Save

Permission problems

If you installed Orange for all users, you should install add-ons as an Administrator. It is probably best to install Orange just for that particular user though. If you do not have administrator access but need an add-on, you can try the following. It might work in some cases. -- @markotoplak

In settings (options-->settings-->Add-ons-->pip install arguments) write this : --user and restart Orange.

It seems that this issue is getting search hits.

[ales-erjavec]

OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

This might be caused by firewall and/or anti virus software.

@sdfungayi Do you have them? Try selectively disabling them to see if they are causing this.

[sdfungayi]

SOLVED
The issue was with my firewall.
The problem persisted when I turned off my firewall. So I turned it back on and specifically opened for C:\program files\orange\python.exe, C:\program files\orange\pythonw.exe and C:\programdata\miniconda3\python.exe
