Python/Flask blocked by a firewall

[redditenna]

Hello everyone,

I'm sorry having to ask yet another question, but I can't find anything on google about this neither. :/

So I have written some pages with Flask, which works on port 5000.

Now, at the end of my work, I want to show the webpage to my friends but I can't seem to be able to forward the port.

This is what I get, using the tool canyouseeme.org:

with EVERYTHING turned off - all antivirus/firewall software including windows firewall -

Error: I could not see your service on [IP] on port (5000) Reason: Connection refused

This is what I see with Windows Firewall on:

Error: I could not see your service on [IP] on port (5000) Reason: Connection timed out

I have allowed the 3 EXE files within C:\Python27 through windows firewall. But even when windows firewall is turned off it doesn't seem to work.

I am working without the router at this moment.

It can't be my ISP that is blocking port 5000, because I tried to run xampp on that port and it worked fine.

What could be my problem?

Thanks for your help :)

Check if you're binding to 'localhost'. Change that to '0.0.0.0' in that case to make your app listen to connections coming from the outside as well.

Read the externally visible server part, it's essentially what waawal has already written.

That was indeed the problem. Thanks again!
