Thingspeak failed to send data

I have an Arduino Nano board. I connect 3 thermistors and they're working and giving correct values on serial monitor.

I connect it via RX and Tx pins with Node MCU Esp8266. Serial monitor from Node MCU also shows me correct data.

My code template and other codes from chat GPT and Google are failed to send data on Thingspeak.
Do you have any idea about it?
That how to send serial data from Node MCU to Thingspeak.

I moved your topic to an appropriate forum category @ubaid12ur.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

I have given you multiple polite warnings about your repeated blatant topic miscategorization. When those didn't work, I resorted to a short account suspension to get your attention. Even that didn't work so this time we are going to try a longer suspension. I hope that on your return you will be more respectful of our forum community. If not, the next suspension will be permanent.

Thanks in advance for your cooperation.
