It currently supports email, Twitter, Slack, Pushover, Pushbullet and others but not Telegram. We will use the webhook notification as the way to send messages to Telegram. IFTTT — bridges UptimeRobot and Telegram by providing the webhook for UptimeRobot and triggering a message to Telegram. In IFTTT terminology: IF {event trigger from UptimeRobot}, then {send message to Telegram group} Telegram — destination of the notification. You will need to create a group for this. Telegram Configuration In Telegram, create a new group, if needed. You may opt to use an existing group. Go to @IFTTT and follow the instruction so link your Telegram account to your IFTTT account.

Dockerfile FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build-env WORKDIR /app # Copy csproj and restore as distinct layers COPY *.csproj ./ RUN dotnet restore # Copy everything else and build COPY . ./ RUN dotnet publish -c Release -o out # Build runtime image FROM mcr.microsoft.com/dotnet/aspnet:6.0 WORKDIR /app # Enable TLS 1.0 RUN sed -i 's/DEFAULT@SECLEVEL=2/DEFAULT@SECLEVEL=1/g' /etc/ssl/openssl.cnf RUN sed -i 's/MinProtocol = TLSv1.2/MinProtocol = TLSv1/g' /etc/ssl/openssl.cnf RUN sed -i 's/DEFAULT@SECLEVEL=2/DEFAULT@...
