A "406 Not Acceptable" error means Cryptohopper received a webhook from TradingView, but the message body was invalid. TradingView successfully sent the alert, but the content was not recognized as a valid Cryptohopper instruction.
Cause
The most common cause is entering the alert content in the wrong field in TradingView — placing it in the Alert name field instead of the Message field.
How to fix it
Go to TradingView and open the alert you want to edit, or create a new one.
In Cryptohopper, generate the correct alert message for your bot.
In the TradingView alert dialog, locate the Message field (not the Alert name).
Paste the generated message into the Message field.
Click Save to update the alert.
Verify it is fixed
After saving, trigger the alert from TradingView. If set up correctly, the "406 Not Acceptable" error will no longer appear in your Cryptohopper notifications.
