I have a program that I use regularly in the UK using the Blink Server without problems. On two separate occasions I have had problems logging in to Blynk from the USA. Strangely Blink does not even recognise my email address from the USA. Is there any explanation for this strange behaviour ? Any help would really be appreciated, thanks.

This will be the problem.

A search of the forums will help too.
Many thanks @Jamin, information you have you have provided has been a great help. Problem solved, I hope!
I’ll test it on my next trip, I needed another excuse to visit the States again

Apparently there is a fix for this coming out so hopefully you won’t have to use this new knowledge for long
