I am trying to use Thrivecart to initiate an order through a sales funnel, which will purchase a print on demand book at the website Lulu. Thrivecart is sending a request to Lulu through it’s API (developers.lulu.com) which will access two PDF’s which are hosted through Bluehost on my website, but my DNS resolver is pointing to Cloudflare.The request is getting rejected with status code 406. I’ve talked with Thrivecart support which said everything is working on there end. I talked to Lulu and they said my file is approved and there isn’t any problem. I talked to Bluehost they checked the log file and said there were some permissions that may have been blocking the transaction through API, however they said since my DNS points to Cloudflare, the issue is with Cloudflare. I don’t have any thing setup in the firewall which could be blocking this on my end in Cloudflare. If anyone can help with this I would appreciate it, since I have not got a response from Cloudflare support.
