FB does not connect to wifi network and app farmbot.io

Hi, I have this problem too. my farmbot was connecting normally until this update, now it does not connect but the wifi network nor the app.
and I do not get error message just does not connect, I’m using configurator 6.4.3 and farmbot.io 6.4.3
Can someone help us?

about 6 days ago it connected without problems.

And the network for configuration only appears when you turn farmbot off and on
