Configuration

Dear reader,

Thanks for reading, I try to setup “Telegram Bot” in HA and run into an error.

“Error from Telegram: httpx.UnsupportedProtocol: Request URL is missing an ‘http://’ or ‘https://’ protocol.”

I sniffed my network traffic and I can confirm, nothing has been tried to https://api.telegram.org. It really get stuck at the add on.

My API is not the real one but for lenght considurations etc…
1234567890:ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghi
Please help me.

Kind regards Ouwekaas.

What did you configure under advanced settings?

Just tried doing the same and getting the same error.
advanced settings are default, so its the same as your screenshot @juergenjw

I’m using broadcast instead of polling. And i use send message only.
Perhaps that makes a difference?

Polling or Broadcast give the same error message unfortunately.

Have the same issue on Raspberry PI HA instance
On my second HA instance (on Mini PC) integration works perfect and I can add bot without any issues. But in second instance in Advanced settings “API endpoint” field is not displayed at all. I don’t understand why the same Telegram integration has different settings between my both HA instances

to fix issue you should downgrade to previous version of HA
or recover from backup or using terminal:
ha core downgrade --version 2026.1.3
It helps me to add new telegram bot

Default settings. Like shown in your picture

This seems to be a bug that was introduced with HA 2026.2.0.

Thank you. I wish developers released every three month instead of monthly.
