Hello, I am uploading data from NodeMCU to the IoT ThingSpeak platform and I have a problem that I do not know where it may come from.

When I upload data from my private Wi-Fi network, from home, I see them correctly and everything works fine. When I upload them from the university network, I do not see it in ThingSpeak. The same software and all the same in several examples. I only change the credentials of the wifi.

Does anyone have any idea what can happen ???

Are you able to update your Thingspeak channel using your browser on the University network? (see https://au.mathworks.com/help/thingspeak/writedata.html for format of URL).

Do you get any return code from the NodeMCU when you try to write? At what point does it fail? Are you able to read data from a channel?

It may be that your University requires you to use a proxy to access the internet.

It is unfortunate that Thingspeak does not have a diagnostic console where you can view the status of incoming requests.
