Send message behind a proxy

[pswrdf]

TelegramLongPollingBot

TelegramApiException: Unable to execute sendmessage method
Caused by: org.apache.http.conn.HttpHostConnectException: Connect to api.telegram.org:443 failed: (connect failed)

I'm behind a proxy and set that way:

RequestConfig requestconfig = new RequestConfig.Builder().setProxy(new HttpHost(phost, pport)).build();
bot.getOptions().setRequestConfig(requestconfig);
new TelegramBotsApi().registerBot(bot);

sending message usual way:

            SendMessage sendMessage = new SendMessage();
            sendMessage.setChatId(chatId).setText(msg);
            execute(sendMessage);

Without a proxy this bot worked nicely

[kagaricyan]

but without proxy i can't receive message from bot；the same time i set proxy and have received message but cannot execute the method execute(send message). can you help me?

My telegram bot works well behind a proxy. I set my proxy config by constructor. Hopefully it can work on your site.

DefaultBotOptions botOptions = ApiContext.getInstance(DefaultBotOptions.class);
if (proxyEnabled) {
     HttpHost httpHost = new HttpHost("proxy_host", proxy_port);
     RequestConfig requestConfig = RequestConfig.custom().setProxy(httpHost).build();
     botOptions.setRequestConfig(requestConfig);
}
MyBot myBot = new MyBot(botOptions);
new TelegramBotsApi().registerBot(myBot)

@pswrdf Does this solution work for you?

@valinz how to set credentials for proxy authentication?

[bvn13]

@rubenlagus I have implemented http proxy authorization (tested on squid3). Please check my pull request https://github.com/rubenlagus/TelegramBots/pull/435 (resent into dev branch)

[valinz]

@bvn13 I don't enable authentication in my proxy server.

[bvn13]

@valinz I reworked the code.

[bvn13]

@pswrdf Please check new functionality https://github.com/rubenlagus/TelegramBots/wiki/Using-Http-Proxy

@rubenlagus Consider to close this issue please.

[KostadinAlmishev]

I fixed it.

[liyaxc]

@KostadinAlmishev I have the same exception, can't solve it for a week... could you please explain how did you fix it? Can you please share that proxy that works?

[liyaxc]

I can't find a http proxy which will work. Does anyone have one?

[bvn13]

@liyaxc I used my own private proxy. Could not share it, sorry. But you could install and use your own one.
