Error sending messages from Telegram bot

[riopedre]

The problem

Some of the messages I send to Telegram using Telegram bot are missing in a random way. I was using notify service. Changed to telegram_bot.send_message service but it fails the same. I have updated to last core version with the same result.

What version of Home Assistant Core has the issue?

core-2024.7.4

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

  - name: telegram_two
    platform: telegram

Anything in the logs that might be useful for us?

Additional information

I'm using a script that send the same message to two different people with different chat_id according to the state of two helpers that enable the sending of the message. In one of the chats I've added 'timeout: 60'. I think that when a message fails, is in both chats but I'm not sure about that.

I have made a new telegram bot two days ago, and changed telegram api key to use new bot. Today I've lost one message. "Error sending message: Timed out" again

Same thing Error sending message: Timed out.

same here (with 2024.8.2) . one test message worked, after that nothing

Approximately 90% of my automations are in Node Red. Until now Telegram notifications were done by calling a Home Assistant script. Last Sunday, I changed these notifications to Node Red directly using nodes from the 'node-red-contrib-telegrambot' palette. Since that moment and after four days, I have not missed any Telegram notifications. I think this indicates that there is a problem with the Home Assistant Telegram_bot integration. Perhaps a library that this integration depends on has recently changed and this error is a side effect. Who knows

[aquashrimps]

the exact same error occurs when sending service messages. At the same time, no such error occurred before the update (2024.6.1 for sure). `homeassistant.components.telegram_bot Source: components/telegram_bot/init.py:717 Integration: Telegram bot (Documentation, problems)

[sermayoral]

II've tried with polling and webhooks, and the same thing happens to me, some messages are not sent due to timeout. It's very frustrating because this worked very well a few months ago. Do you know of any alternative without using Node-Red? Thank you very much.

Sorry. I don't know any alternative of Telegram notifications without HA or NodeRed. With NodeRed, I don't have any problem. You can change to another notifications platform alternative like HA Companion aplication.

Hi , i want to share with you how i arrive to avoid to have this issue actually. To solve that I stop the extension Adguard Home. Since that i do not have anymore this time out. Look like something is not ok with both working together.

Hi , i want to share with you how i arrive to avoid to have this issue actually. To solve that I stop the extension Adguard Home. Since that i do not have anymore this time out. Look like something is not ok with both working together.

I have Adguard Home installed. But i don't want to disable it. I have compared my HA logs to see when I've lost a Telegram message and compare with Adguard logs to see any coincidence, any DNS request denegated by an Adguard filter and I can see nothing. It would be nice if the rest of people that has the same problems with Telegram messages could tell us if they are using Adguard Home. Thanks

[sosso-b]

It's was not a pleasure for me to do it because I need it to but due to the fact no one was helping on this issue I was testing a lot think. An till now since and chance the DNS on my server and do not pass the traffic via Adguard I can tell that no more 1 time out with telegram. Then for me this was the issue. But in the past I have Adguard and telegram working great. I don't know what happens. But yes if someone can like you share information that would be great 😃

[aquashrimps]

the problem with Adguard is clearly indirect, because I don't have it, but there is a problem. Therefore, it is worth considering other possible options, rather than relying on only one Adguard...

[sosso-b]

Based on your information, I'm considering that something in the network configuration may be causing delays in sending and responding to Telegram requests, leading to this timeout error.

For me, it was Adguard, but for others, it could be any DNS filter.

Anyway, thank you for the information!

[oxelwhy]

Yeah, same issue, "Error sending message: Timed out. ". Tested using POST direct sending on the network, meaning isolated due to network blocking. Likely due to Home Assistant's telegram_bot setup.

My Home Assistant version is 2025.3.1. The problem sending Telegram messages persists. Today, I have four messages lost: "Error sending message: Timed out".

I'm currently using Home Assistant version 2025.7.2. Due to bugs in the Telegram bot, I've switched 99% of my messages to Node Red. Currently, I haven't encountered any bugs in my occasional use (1%) of the Telegram bot in HA. Perhaps other users are still experiencing this issue with the Telegram bot.

[kerryland]

I'm experiencing this in 2025.9.3, but the messages are actually being sent.
