I made my first Iot project and it worked fine. When I closed my computer and tried it again my device esp32 was offline and i can't get it on line again!

It might help if you post your code.

Is that offline as in not connecting to a network or offline as in not connecting over serial/USB?

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project.

Even connected to Arduino IoT Cloud, the device says offline.

It`s a bug from Arduino IOT cloud side, It shows offline but device actually works..

Hello,
I,am facing problems with the offline of a esp32 devkit v1.
Yesterday it was on line today no way to have it online.
All worke like updating the sketch and uploding. the agent is running.
this is what i read on the serial monitor,
ArduinoIoTCloudTCP::handle_ConnectMqttBroker could not connect to mqtts-up.iot.arduino.cc:8884
ArduinoIoTCloudTCP::handle_ConnectMqttBroker 5 connection attempt at tick time 113851
Howe to solve this problem?
As a low profile user free account I deleted all of my iot devices only one is present.
Mobile is running for test .
like to hear.

I keep getting this problem. Arduino IOT Cloud too frustrating to work with. Is Blynk worthwhile?

Last week, it worked just fine. Then I change a little code which compiled properly, but this ESP32 is again offline. Checked for firewalls - change agent is allowed to pass. Passwork to network confirmed correct. device is associated with Thing. etc.

Very frustrating. Big hole in Arduino.

My buddy swears by the Adafruit cloud. Looks kind of 1990-ish, but if it works and it's less frustrating,

my time is worth the switch. I can't get those hours back.

Any comments out there?
Adafruit? Blynk?

I tried Blynk a few months ago and found it odd. In the pursuit of money they are clearly shifting their focus from the hobby world to the corporate world.
Perhaps this is why I found the support forum to be more sales support than technical support. For example I asked about the possibility of using a non-standard configuration and the response was "why don't you try it and tell us if it works" which was no help at all. There wasn't even an offer of "we'll investigate and get back to you".

Thanks

I tried it out today. Blynk is trickier. If the learning curve is too steep, then they are doing it wrong. My time is over valuable

I think it`s not the cloud, I had the same problem few days ago, and the problem was updating board core for ESP32. If you updated the core to the latest version, just uninstall it and install again, after that, upload your code again and it should work...
