I quickly looked this thing up because I had never heard of it.

Anyway, if it all starts working again after 5-6 hours, it is possible you are hitting a usage limit (maybe because of an error) :

Please edit your first post to put the code between code tags. Maybe you also don't want to expose your passwords etc. in the post.

I'd be most concerned about the BOTtoken value you published. It that's supposed to be a secret then you should expire that token in your Telegram account immediately.

Unless you reuse passwords, I'm not sure publishing a WiFi SSID and password is that big of a deal since that's only useful within the range of your WiFi router.
