The notice on my Teslafi account is:
“TeslaFi and third party cloud hosted services are currently unable to communicate with Tesla's servers. We are currently working on finding a solution and will provide an update when one is available.“
On Twitter, Teslafi’s post is:
It appears @tesla may have blocked access to the API from @awscloud or it's just a temporary issue but all calls are timing out. Currently trying to find out more details. @tesla ?
At question is whether this is a deliberate block from Tesla or an outage?
