Sounds like it could be coincidental timing. The first thing I would try is to reauthorize your smart home hub:
- Open your SharpTools.io User Page
- Tap the Manage Connections button
- Select your smart home hub and follow the prompts
If you’re referring to the Weather Tile - Open Weather - Current and Forecast custom tile, all of the custom tiles run in their own sandbox so they aren’t capable of impacting other things on the dashboard (or your account).
If you still experience the issue after that, you could also try accessing thing from your mobile phone while disconnected from your WiFi to help rule out network related issues.
