Bot looses connection to server and fails to establish a chat-connection

[A-Ortner]

Describe the bug
The bot fails to establish a chat-connection to a user, because the server couldn´t recognize the bot anymore via it´s key-set.
The bug occured after the WoN had been excessively used all day.

To Reproduce
Steps to reproduce the behavior:

1. Start your bot a couple of times (approximately 10x)
2. Start a chat every time.
3. Problem: After a certain amount of time, you will see that not even the initial message ("Hello, I am...) is sent anymore.
4. Bot cannot be further used.

(this is also the case when the user´s message is sent, here the user´s message is still being sent)

Expected behavior
Normally, the bot should answer your chat request.

Desktop (please complete the following information):

• OS: Windows 10
• Browser Firefox
• Version 70.0.1

Additional context
The problem can currently be fixed through deleting the bot´s key-set. After starting the programm again, it will create a new key-set and everything continues to work. However, there should be a 'reset'-option the user can use as well.
