#### What is the problem you are having with rclone? I'm getting an error when I try to access B2 through Cloudflare. However, when I try to view the same URL / file with curl, it works perfectly: ```auto curl https:///test.txt ``` #### What is your rclone version (output from `rclone version`) rclone v1.54.1 #### Which OS you are using and how many bits (eg Windows 7, 64 bit) Debian 4.19.0-14 #### Which cloud storage system are you using? (eg Google Drive) Backblaze B2 #### The command you were trying to run (eg `rclone copy /tmp remote:tmp`) ```auto rclone cat --http-url https:///file//test.txt :http: ``` #### The rclone config contents with secrets removed. Calling URL directly in the command, it is not using config file. #### A log from the command with the `-vv` flag ```auto ERROR : : error listing: error listing "": directory not found Failed to cat with 2 errors: last error was: error listing "": directory not found ``` ---

Hello @TowerBR - nice to see you again 🙂 The http backend requires directory listings to work which don't with the b2 bucket exported via cloudflare. If you want to use rclone to download a single file you know the name of then use ``` rclone copyurl https:///file//test.txt ``` If you want more "syncing" abilities then investigate the [--download-url](https://rclone.org/b2/#b2-download-url) parameter Hope that helps! ---

Hello @ncw, Rclone is my daily tool, my real "Swiss army knife of cloud", and sometimes I try to do something "different" and I encounter problems. 🙃 I actually want to copy / move hundreds of GB out of B2, and I would like to avoid download charges. I've already done some tests with the `--b2-download-url` parameter, but I was afraid if the download was really coming from the custom endpoint. For example, when testing the command ```auto rclone lsd : --b2-download-url=https:///file// ``` it returned all buckets (according to the first parameter, where I did not specify buckets, but all storage), and not just the `` objects. How can I check if the downloads really come from the custom endpoint? ---

When you use `--b2-download-url` it uses normal B2 endpoints for all the API stuff but used the cloudflare URL **only** for downloading files. So what you found above is what I'd expect. If you want to double check where the downloads come from use `-vv --dump headers` which will show the HTTP headers in use - you can check the downloads from there. So you want to set up your cloudflare domain [cdn.example.com](http://cdn.example.com) which has a CNAME pointing to [f000.backblazeb2.com](http://f000.backblazeb2.com) (or whaterver the right name is for you) Then you pass `--b2-download-url https://cdn.example.com` Interestingly I found a very small bug which made it so you couldn't download HTML files via cloudflare as it strips the Content-Length form the header whch rclone was relying on. I just merged a fix for that to [the latest beta](https://beta.rclone.org). ---
