And another observation… please repost both the serial monitor output an the actual sketch that generated it… you two prior displayed are NOT one from the other, as evidenced in the time printout: If you changed that, what else might you have changed that could generate the 2nd connect msg?
I took out the blink.connect loop and the 2nd connect is now gone.
I still have a problem:
Wake time sometimes (every 30-40 times) goes to over 300 seconds… when it is normally 2-4 seconds.
Here is the updated output.

Sounds like something gets ‘stuck’ in the Blynk.begin() call.
I am now doing WiFi.begin and it seems to speed things up. (big delays in Blynk.begin…???)
I also had to resort to a sort of watchdog to get past these 300 seconds events…
I now get ‘wake time’ of ~1.9 seconds 90% of the time and once in a while, eit goes up to 2.98 and even up to 4,92 sec.
Watchdog kicks in ~1% of the time. (no connect for >15 seconds) so no big power on for 300 seconds.
