Failed to login API

[seanyan1994]

My integration suddenly failed to start up. I attempted to reinstall the integration, but upon logging in, I received the following error. "Failed to login API: An error occurred when connecting to MQTT endpoint." "MQTT connection failed with exception AWS_ERROR_MQTT_UNEXPECTED_HANGUP: The connection was closed unexpectedly."

I also encountered this error. It started appearing around the same time.

I got this issue also, I'm on the tag 1.0.0:

Exception ignored in: <function JciHitachiAWSAPI.login.<locals>.get_credential_callable at 0x7f17311b7010>
