Problem with Telegram Webhook Using Google Apps Script

[Bowo Work]

So basically, I created a Telegram bot to add data sent from Telegram to a spreadsheet. I created a few bots, and all of them work fine with almost identical scripts. These bots send data in private messages to the bot, which then stores all the data in a spreadsheet.

Now, I am trying to create a similar bot, but in this case, the users will send data from a group, not privately. The problem I am facing is with the webhook. I use the same webhook function:

function setWebhook() {
    var url = telegramUrl + "/setWebhook?url=" + urlPublish;
    var response = UrlFetchApp.fetch(url);
    Logger.log("Webhook Response: " + response.getContentText());
}

In private, it works perfectly. However, in a group, after 30-40 minutes, the bot stops responding. When I check the webhook info using:

https://api.telegram.org/botTOKENHERE/getWebhookInfo

I find the problem. Initially, after running the script, the response looks like this:

{
"ok": true,
"result": {
"url": "https://script.google.com/macros/s/XXXXXXXX/exec",
"has_custom_certificate": false,
"pending_update_count": 0,
"max_connections": 40,
"ip_address": "216.58.206.46"
}
}

But after 30-40 minutes, the URL value changes to:

{
"ok": true,
"result": {
"url": "https://technical-webhook.fun:8443/webhook/XXXXX",
"has_custom_certificate": false,
"pending_update_count": 0,
"max_connections": 40,
"ip_address": "188.114.96.3"
}
}

Can someone please help me understand what is happening?

What I imagine it's not possible auto change webhook url you can deeply check May be some code or your token compromise and someone doing this

Change the group to supergroup and assign your bot as an admin

Also you have to use doPost and don't return ContentService!
