.\simpleshell.exe *** 149.154.167.40:443

cjongseok commented 6 years ago

Can you try it again after removing ${HOME}/.telegram_*** file?

zkip commented 6 years ago

Yes,i tried.This is the result of the trial.

cjongseok commented 6 years ago

oh sorry, please try it again after setting sessionFileHome = ""

cjongseok commented 6 years ago

are you in China?

zkip commented 6 years ago

Yes.

cjongseok commented 6 years ago

Then can you try it over VPN?

zkip commented 6 years ago

Do you mean that I was blocked by a firewall?

cjongseok commented 6 years ago

I think so. There is a case which an application encountered "the connection was forcibly closed" in China but VPN thru Hong Kong. See Ludovic Boudinet's comment on https://archive.sap.com/discussions/thread/3232185

zkip commented 6 years ago

Well, I see. Thank you for your answer.

cjongseok commented 6 years ago

It's my pleasure. If you try it over VPN, please share the result then other guys can refer it. Thank you :)

zkip commented 6 years ago

I will.

zkip commented 6 years ago

But it's strange that I was successful when I Ping the remote host.

zkip commented 6 years ago

Maybe you should add the capability to use a proxy? For example, socks5.

cjongseok commented 6 years ago

Can you check the port 443 is reachable from your PC? On Windows, you can use telnet. see https://www.acronis.com/en-us/articles/telnet/ Unfortunately, I have no plan to add socks5, sorry. I hope VPN would work. If you really need mtproto over socks5, I think you can refer to this open pull request. According to mtproto.go:82-98, it seems you can just alternate net.DialTCP() with socks5.Dial() after socks5 instantiation.

zkip commented 6 years ago

It was true that I was blocked by the firewall, and finally I solved this problem when I used the Socks5 agent.
