Telegram,smtp,fitbit not working in 0.47.1

Good morning
I have updated to version 0.47.1 the notifications of Telegram and email no longer work automatically. If the triggers manually work instead.
From the documentation on the site I do not understand if I have to change something in configuration.
Today I found the following error concerning telegram

ERROR (MainThread) [homeassistant.components.telegram_bot.polling] Client connection error

Regarding the email I have no errors in the log but do not arrive.
I used the SMTP of Yahoo smtp.mail.yahoo.it

Regarding Fitbit in the log I have the following error that I can not interpret. The configuration on the site Fitbit is correct

Thanks for the support

I don’t use fitbit or email, but Telegram is definitely working here - I only set it up the other day as a replacement for pushbullet as I can send pictures out, and react to messages sent back.
