Use system proxy if set

[Unin777]

Hi

First of all, thank you Ritiek for your great project, I really love it,
yesterday I started to work with this bot, and I have my but running on VPS, and everything works find, except one thing.

As you guys may know Telegram is banned in some countries, and users from those countries use VPN in order to use the telegram. However, I gave this but to a friend of mine which lives in a country where Telegram is banned, and he got errors from the console, which indicated that couldn't establish a connection. Notice that he also had a VPN running, but still had the same problem. I wanna know is there a way around this? As I'm a beginner in Python, I can use your help to improve my rat.

The requests need to go through the VPN proxy. We could add something like this. Is this the same error you get when trying to connect without a proxy?

Yes it is, it is also the same error when you are not connected to the internet

As per a quick fix, you can set the following lines before instantiating the Bot object:

proxy_url = "http://proxy.server:3128"
telepot.api._pools = {
    'default': urllib3.ProxyManager(proxy_url=proxy_url, num_pools=3, maxsize=10, retries=False, timeout=30),
}
telepot.api._onetime_pool_spec = (urllib3.ProxyManager, dict(proxy_url=proxy_url, num_pools=1, maxsize=1, retries=False, timeout=30))

Change the proxy url/port and you should be good to go. Tell me how it goes

Thanks for your quick response, I wanna ask, how should I set the proxy url? I mean from where I can get a proxy server? Is there a way my bot can use the VPN that the user is using?

As to my knowledge, I dont know a free proxy server which is stable enough to use in the rat

[mvrozanti]

Yes, there is a way to connect to a VPN that is not on your local computer. For this, you need a proxy server running publicly. The proxy_url variable would then contain the address/port of that server.
