Log in problems with new ios version

Newest ios
newest blynkserver
Upon the last ios update, I have lost connection … at the blynk login screen I get the message…
you have no internet connection

I did check the port … I have been using 9443 for sometime now.
I have rebooted everything.
I am using a raspberry pi for server. I can log in using dashboard.

Hello. Probably 9443 port blocked in your setup?
