Not reconnecting after WS timeout

[Exanlv]

Looks like the lib doesn't reconnect to Discord after a missed heartbeat ack.

• [x] Add more logging around websocket connection attempts and its error handling
• [x] Validate whether this is indeed the reason for the disconnect after a few days of running
• [x] Fix

Issue is caused by a timeout when connecting

When this happens, a new connection should be established with the default wss url

Fix should:

• Reconnect to WS on default URL rather than recover URL
• Try 3 times
• If 3 consecutive fails, shutdown

In the refactor branch, following error occurs
