6 years ago FYI: I did a restart of the access point, waited a few minutes and ESP didn't reconnect. Then did a hard reset of the ESP8266, and it started talking to fermentrack again.

6 years ago This has been happening again lately - have done restarts of both my esp8266 controller and the fermentrack server to no avail. The LCD on the controller indicates it is still doing what it's supposed to. I include the most recent traceback below.
I went to the admin settings and changed the last cached ip address to what the controller LCD showed during it's most recent boot (they were different), and that fixed everything. So perhaps there is a more graceful way to handle unexpectedly changed IP addresses of controllers here. For the future I'll just set some DHCP reservations for my controllers. May be good to have a recommendation for static IPs somewhere if it doesn't already exist.

I am encountering this when I go to debug an ESP8266 which is currently failing to connect (which is on v0.10 firmware, so somewhat unexpected in of itself, will investigate further). Cheers.
