1. Check API Key and Channel ID
Ensure that the API Key and Channel ID used in your HTTP request are correct. An incorrect API Key or Channel ID can lead to failures in data transmission.
2. Data Formatting
The format of the data being sent must match what ThingSpeak expects. ThingSpeak requires data to be sent in a query string with field names as field1, field2, etc., depending on how many fields are set up in your channel.
Example format:
GET https://api.thingspeak.com/update?api_key=YOUR_API_KEY&field1=0&field2=100 HTTP/1.1
3. Connection Limits
ThingSpeak has a limit on the rate at which updates can be sent, which is once every 15 seconds for free accounts. If you exceed this rate, you will not be able to send more data until the time limit has expired.
4. Maximum Field Limit
ThingSpeak channels have a maximum of 8 fields. Ensure you are not trying to send data to more fields than your channel has configured.
5. Network Issues
Check your network connection. Sometimes, intermittent network issues or wrong network settings (like proxy configurations) can cause failed requests.
6. Content-Length Header
If you are sending data using POST method, ensure that the Content-Length header in your HTTP request correctly matches the length of the data you are sending.
7. Debugging the Request
Try to isolate the issue by sending a simple request with minimal fields and gradually add more data to see at which point it fails. This can help identify if a specific piece of data or format is causing the issue.
Ensure that your requests are correctly formatted, adhere to the API limits, and contain valid API credentials. Testing with simplified data can also help identify the source of the issue. If you provide more specific details about the request format and the actual code you are using, I can give more precise advice.

You can send data to multiple fields in a single post by adding &fieldx=number to the end of the api call or the mqtt payload. Be sure to replace x with the field number of interest and 'number' with the data you wish to send.
I dont think there is an http error code 210, there is a response code that means 'sucessfully connected'. Perhaps you can provide more context around the error. What is happening in the code when you get that?
