Cannot connect to host - All sensors/forecast unavailable #272

Description

@Airforc

Recently, my forecast and sensor status has gone unavailable. The integration is not failed, and the API key is valid.

I checked the log and it is reporting that the hostname swd.weatherflow.com cannot connect due to a SSL hostname mismatch.

I did check the SSL certificate from the weatherflow website and while it is a wildcard cert it is valid and the hostnames match. Not sure why HA/integration is complaining about the mistmatch.

Not saying this is a problem with the integration, maybe I am too far off my meds. Anyone else have this happening?
