App for Cloudflare® Pro 1.9.2

[VidiMan]

I got the plugin installed and the token activated with a green check mark. And that was it evidently. I can't seem to connect to a bucket and nothing is working. Claude code told me to dump it because nothing works in your plugin with R2.
App for Cloudflare is BROKEN for R2 - that's your problem right there. Here's the FREE solution that actually works:

Ditch That Plugin


1. Delete "App for Cloudflare"

- It's useless for R2

What exactly isn't working? Are you getting any specific error? Also there is no "green check mark" when your API token is enabled... are you sure you are looking at the right plugin?

Maybe there's some confusion in that the R2 functionality is part of the Pro version, not the free version from wordpress.org (if that's what you are using)?

"Claude code" is correct though... App for Cloudflare does not work with R2 without a Pro license, App for Cloudflare Pro is what you would want.

I also can't get the R2 function to work. This is the only issue I'm having with the plugin. My Token privs are all green.

When I go to R2 there are no buckets being created.

I also see this error occasionally:

Last App For Cloudflare® error:

Cloudflare: http_request_failed: cURL error 35: OpenSSL/3.0.13: error:0A000410:SSL routines::sslv3 alert handshake failure

Edit:

I created the bucket and it started to work, it's uploaded 5 files, but then it reports a critical wordpress error. It seems to be erroring out on large video files.

Do you have shell access to your server? The sslv3 alert handshake failure error is saying the server is having an issue communicating with Cloudflare’s servers (most likely the server is trying to use an old/outdated SSL/TLS version that Cloudflare isn’t supporting).

i do. i can ssh in. I fixed the SSL error, I believe. I haven't seen it in a while after I made SSL less strict.

The issue now is that I can only get one 206MB file to upload to R2, then I get a critical server error.

edit: I enabled debugging. It's a memory issue.

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 271017120 bytes) in /mnt/volume1/html/html/wp-content/plugins/app-for-cf-pro/src/DigitalPoint/Cloudflare/Base/PubAdvanced.php on line 248

I have a lot of large media files to transfer so I'll move everything to a server with more memory to get this done.

Odd... I believe the API endpoints use the 2 newest options (TLS 1.2 and TLS 1.3), anything else is old and has security issues so they disabled using older SSL/TLS versions.

Not so coincidentally, changing how files are uploaded (as a stream rather than loading into memory) was rolled out in the XenForo version of this addon a few weeks ago:

[DigitalPoint] App for Cloudflare® - Updates

xenforo.com

...the WordPress update is still being tested, but I'll see if I can get it released today for you.

Sweet. That's rad. I already performed the server migration in hetzner(damn they make it easy). So I'll see if 4gb of ram will get it done.

Ya, the quick work around (before I get this update rolled out) is to temporarily up the memory PHP can use (enough to fit the largest files you want to migrate into memory).

lol yeah I'm dealing with 1+gb video files so I'll see what I can do. The error is happening on relatively small files of less than 500mb, so idk.

I'm still getting some warnings but they are transfering. I upped the memory limit to 3.5gb.
