Telegram Http.Get first message Status 202 (Ok) but following messages return Status=0 ?
27 Mar 2025, 15:07
I am using Http.Get towards Telegram and it has been working fine for many months.
Just recently only the first message in an instance works, then any following messages from that instance do not work (response status=0).
There has been a cTrader update to 5.2.5 which may be the culprit, not sure.
Are others noticing the same behaviour using Telegram ?
Would someone please have a solution for me ?
using cAlgo.API;
using cAlgo.API.Indicators;
using System;
using System.Linq;
using System.Collections.Generic;
[Robot(AccessRights = AccessRights.None, AddIndicators = true)]
private void SendTelegramMessage(string Message, string TelegramToken, string TelegramChatId)
{
// Send message to Telegram
var result = Http.Get($"https://api.telegram.org/bot{TelegramToken}/sendMessage?chat_id={TelegramChatId}&text="+Message);
switch(result.StatusCode)
{
case 0:
Print("Telegram: Status " + result.StatusCode + ": The bot sleeping, wake it up.");
break;
case 200:
Print("Telegram: Status " + result.StatusCode + ": Message sent -> " + Message);
break;
case 400:
Print("Telegram: Status " + result.StatusCode + ": The chat id (" + TelegramChatId + ") is incorrect.");
break;
case 401:
Print("Telegram: Status " + result.StatusCode + ": The bot token (" + TelegramToken + ") is incorrect.");
break;
case 404:
Print("Telegram: Status " + result.StatusCode + ": The bot token (" + TelegramToken + ") or chat id (" + TelegramChatId + ") is missing or incorrect.");
break;
default:
Print("Telegram: " + result.StatusCode + ": Unknown error code.");
break;
}
}

Hi,
same error here... it's a bit frustrating, when you have a code that has been working for months and then you get an unexplained error.
As a developer, I started saying that my code had a problem.. look for a solution.. look here ... look there... but then to my surprise, the problem was an update! well here not having full control of the HTTP library..
I just have to wait for a solution.. or go back to 'FullAccess' mode using the classic httpClient. I wait confidently. Thanks

FullAccess mode and classic httpClient doesnt solve the issue for me. Could you give an example for, how this would work right now? I would directly use it..

For now, I have moved away from Spotware cTrader 5.2.5 to a previous version using broker provided cTrader (IC Markets 5.1.14). It is working fine.

Same problem here. I've tried a lot of "solutions," but nothing works.
If I use this Print: Print($"Exception: {response.Exception}");
I get this:
Exception: cAlgo.API.HttpException: System.InvalidOperationException: This instance has already started one or more requests. Properties can only be modified before sending the first request.
Update: I talked with Spotware support and looks like that is a bug.
We are currently addressing the issue and conducting a thorough review to ensure a proper resolution.
The temporary solution is to install an older version of cTrader.

Can you keep us updated, if you get new information?
