You're right. Tnx. But why does my other products work WITHOUT the wifi-connection block? Have burned a variety of M5sticks/Atoms without having to use the block. If it's mandatory, why not use it in the UIFLOW examples?

SOLVED - KINDA
Yes, this is a browser issue - and a BUG really

Changing the browser WILL solve the problem - temporarily - until you open a NEW TAB with another uiflow instance and another M5 connection, i.e an M5Stick. Apparently the underlying issue is that the browser (caches, cookies?) saves some display settings, i.e FONTS etc, and this causes the WSOD.

M5 team - fix this stuff man, it makes the product seem so unreliable when it's really just a bad web-coding issue

This is so simple, its unbelievable it really happens. I turn on a brandnew Core2, connect with UIFlow, drag a labet to the screen and hit Run. Screen stays white.

This has been published before, but it is really both obvious and a major bug. Simple to describe: MQTT never connects or works after you burned your software to the M5Core2

UIFlow load button not responding

Works in Safari

Chrome/Mac

@pieter no, you DONT need a chinese server, that's whats puzzling. But what I am wondering is these elements put together:

I can see flow.m5stack.com, but not connect to any M5
My preprogrammed M5's are running their LOCAL code stuff (ligthing, buttons etc), but NOT communicating through MQTT - maybe they don't have connection at all, but WHY would THEY loose connection? Why on earth is their network capabilities suddenly lost?

Maybe, I thought, there's a server somewhere keeping track of API keys or something - like a DNS - and that ones broken?

So MQTT works with a server yes, but that can be ANY server ready to distribute messages from IOT devices.
There's a few free ones for testing, ie https://test.mosquitto.org/. But in my school, I've set up a server myself, so we can go nuts without breaking stuff. It's super reliable and fun to use.

@arno did you also test connection to an M5? I get the webpage, but no connection

It is up - but wont connect (Denmark)

Also - really weird - none of our burned devices are networking. We have a bunch of previously programmed M5sticks /Atoms running MQTT - they don't send or receive messages. What does that even mean? Is there some kind of central server ANY M5 will have to establish connection to in order to use networking?

White screen here in Denmark - no matter what browser or network

So, I can't load the webinterface to UIFLOW on any browser or network connection from copenhagen, denmark.

The console informs the following:

Failed to load resource: net::ERR_INCOMPLETE_CHUNKED_ENCODING
main.1685f54dc91eb35eda91.js:1
Failed to load resource: net::ERR_INCOMPLETE_CHUNKED_ENCODING

Which to my best interpretation would seem, theres a faulty deploy of the servers javascripts.
