Fix API fetch failures

[TheHolyRoger]

Since coingecko has currently disabled the API endpoint, I think I was helping to DDOS the server with endless retries to update the state :)

Wrapping the request in this try statement resolves it for me and will (try to) fetch the next update on the interval instead of endlessly looping

Seems like a good solution. Thnx!
