Telegram and Discord gives " invalid endpoint URL"  

Telegram and Discord gives " invalid endpoint URL"

Prusa mk4 

firmware: 5.1.2+13478

Problem:
I have followed the guide to telegram bot. I get the message saying 

"Hi, I am your first notification, thank you for using them. You can adjust the sending of notifications according to your wishes."

I also get the evrything is OK "check" on prusa connect 

Then on the first notification the checkmark change to a error mark saying something like " invalid endpoint URL"

I then tried the same with Dicord. Got the same initial message. ANd on the first finished print when the message should go out. I get "invalid endpoint URL" in the prusa connect backend. 

Tried:
Delete and adding again. The same happens. New initial message and then Error on the first try to deliver notification. 

I also found this post: https://forum.prusa3d.com/forum/general-discussion-user-experience-ideas/telegram/#post-635600 that i have not tried since i like discord best. And wanted to get Discord to work. 

Any suggestion ?`
