Getting a 406 Error Code - What’s Causing It and How Do I Fix It? or Why Am I Seeing a 406 Error Code

406 error code? Sounds like your server’s being a diva.

Quick fix: Try sending a blank Accept header. Sounds weird, but some servers default to a sane format if you don’t specify.

Also, if you’re using Cloudflare, turn off "Rocket Loader"—it messes with headers sometimes.

For tools, check out "HTTP Toolkit" (httptoolkit.tech). Lets you see exactly what’s being sent/received.
