Telegram alerts seems to be broken

Checked, removed all old transport and old rules, and create new ones under alerts to be sure.
Created a new bot based on this document : Transports - LibreNMS Docs
From there there is a small corrrection needed in the document. After creaton of the bot, you need to start the url to activate the bot otherwise the bot will anwer the url in de example with : {“ok”:true,“result”:[]}
After talking to the bot then you get the jason result back.
But , after the whole procedure … no luck
the message pop ups and then no further actions possible.
