Telegram notifications timing out - failed to send using telegram: timed out

[aronmgv]

Describe the bug

Hello,

I am suspecting that shoutrrr is already a dead project.. I reported problem there and notice their issue tracker is pretty much abandoned.. so posting it here.

I am trying to configure watchtower but getting failed to send using telegram: timed out no matter what configuration I use for WATCHTOWER_NOTIFICATION_URL.

services:
  watchtower:
    image: containrrr/watchtower:latest
    container_name: watchtower
    environment:
      - WATCHTOWER_DEBUG=true
      - WATCHTOWER_MONITOR_ONLY=true
      - WATCHTOWER_LABEL_ENABLE=true
      - WATCHTOWER_NOTIFICATIONS=shoutrrr
      - WATCHTOWER_NOTIFICATION_TIMEOUT=30s
      - WATCHTOWER_NOTIFICATION_URL=telegram://111:222@telegram?chats=333&preview=No
      - WATCHTOWER_SCHEDULE=0 * * * *
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    restart: always

watchtower  | time="2025-02-09T20:40:46Z" level=error msg="Failed to send shoutrrr notification" error="failed to send using telegram: timed out" index=0 notify=no service=telegram

I tried every single possible configuration for WATCHTOWER_NOTIFICATION_URL still no luck :/

Then I found one user posting it is possible to get this URL generated via: docker run --rm -it containrrr/shoutrrr generate telegram which I did and it gave the the following URL format: telegram://111:222@telegram?chats=333&preview=No. This is when I want to send notifications to the bot chat directly (yes i started conversation with bot prior)..
I tried using private channel with same time out error..

I tested it directly using containrrr/shoutrrr:latest and sending commnad:

docker run --rm containrrr/shoutrrr:latest send telegram://111:222@telegram?chats=333 "Test message from Shoutrrr"
failed to send using telegram: timed out

I confirm bot is configured correctly sich I get message via POST:

curl -X POST "https://api.telegram.org/bot111:222/sendMessage" -d "chat_id=333&text=Test"
