Security 1.0 - Random corruption?

[jeeftor]

This is the 3rd time a specific situation has happened with my device and I'm not sure I'll be able to provide useful debugging info.

• I start getting errors in the MQTT logs about authentication, the web interface dies. I can still ping the device but it basically stops responding to anything.

Just hard booted and nothing so I'll probably have to reflash it I'm thinking...

Connected via flash tool and here are my logs:

I'm seeing similar things in MQTT:

Let it be known - nothing has changed in the MQTT Configuration... so I'm not sure whats happening.

The only thought I can come up with is it got into some sort of loop thats retrying so fast the webpage wont load.

After a re-flash -> same username and same password everything is peachy again...

I wonder if we get into an authentication issue over and over again whether adding some sort of back-off ... (drop to once every 5 seconds) might help things out... I've seen other IOT devices end up in a similar type of deadlock on occasion

(Also happily awaiting the ESPHome version for security 1.0:) )
