Does PythonAnyWhere block outbound connections?

Hi!

I'm new in PythonAnyWhere, and im trying to send some POSTs to a webserver from my webapp. This webserver runs on port 4043.

Maybe its a firewall blocking this connection? Is possible to allow this TCP port?

Thanks

It looks like you had a free account when you posted this, which would have blocked outbound connections to sites that aren't on our whitelist -- I see you've upgraded since then, so hopefully everything should be working fine now...?

Hi Giles, everything is Fine! Is There a way to fix a static IP for outbound connections? Or a name?

Thanks

No, outbound connections will come from whatever server your code is running on.

Is there a way to allow inbound connections to web app only from certain IP addresses?

You can do it in your code, and just drop requests from outside your list.

Outbound requests to api-halls.slot7lan.com get 403 Forbidden from the proxy (Tunnel connection failed).
