I am using a container name that doesn’t exist. * [http://wordpress.org/extend/plugins/updraftplus/](http://wordpress.org/extend/plugins/updraftplus/) Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [David Anderson / Team Updraft](https://wordpress.org/support/users/davidanderson/) * (@davidanderson) * [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866539) * Hi davferg5000, * Does your web server have curl installed? (If it does not, then UpdraftPlus should be warning you – but you can also click on the ‘Expert settings’ and then scroll down and click on the ‘show PHP information (phpinfo)’ link. In the window that pops up you should be able to find a line “cURL support enabled”. * Presuming that that’s not the problem (as I say, it should say so, if it was), then it looks like your webserver is not managing to contact Cloud Files at all. Does your web host have restrictions on outgoing traffic from websites? * David * Thread Starter [davferg5000](https://wordpress.org/support/users/davferg5000/) * (@davferg5000) * [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866540) * It does have curl. The site is hosted on azurewebsites. The same site does have W3 Total Cache plug-in which uses Rackspace Cloud Files as the CDN and that works fine, so I think there is no issue with connecting to rackspace. Perhaps W3 Total Cache conflicts with Updraftplus? * Plugin Author [David Anderson / Team Updraft](https://wordpress.org/support/users/davidanderson/) * (@davidanderson) * [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866544) * Thanks for the info, that’s helpful. * There shouldn’t be a conflict at this point, as the test does a fairly simple operation. * Interestingly W3 Total Cache uses the same Cloudfiles library as UpdraftPlus, so in theory this should not be tricky. (In theory it should not be happening at all!). * Try this: go into the expert options, and toggle the ‘use server SSL certificates’ option. Then try the test again. * Thread Starter [davferg5000](https://wordpress.org/support/users/davferg5000/) * (@davferg5000) * [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866550) * I checked that (was unchecked) same thing. I also checked each of the other SSL options individually but same results each time. * I verified the CDN was working on W3 and it is enabled and working. I looked at the PHP info and curl is enabled and no warnings coming from the plug-in. * Plugin Author [David Anderson / Team Updraft](https://wordpress.org/support/users/davidanderson/) * (@davidanderson) * [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866554) * Aah… looking in the W3TC code, I think I see the problem. * Both UpdraftPlus and W3TC include a version of the same CloudFiles library. W3TC doesn’t namespace its library at all; UpdraftPlus namespaces some parts of it, but I missed some. As a result its conflicting. * Please update to the new development version (uploaded just now – should show as version 1.6.24), and try again, and let me know how you get on… * David * Thread Starter [davferg5000](https://wordpress.org/support/users/davferg5000/) * (@davferg5000) * [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866561) * I have 1.6.24 running now and same error. I deleted the plug-in and select delete all files, I do notice that when I reinstall my settings are still there (the rackspace connection info). So not sure if I am doing a complete reinstall or not? * Plugin Author [David Anderson / Team Updraft](https://wordpress.org/support/users/davidanderson/) * (@davidanderson) * [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866588) * Hi, * There’s a “Wipe Settings” button in the ‘expert’ section, but that shouldn’t make any difference in this case – there’s no evidence that the settings are being mis-saved. * That the same happens makes sense, actually – if the W3TC + UpdraftPlus libraries were clashing then we’d expect WordPress to crash rather than complete the test with an error message. * Can you try disabling all your other plugins, and seeing if that fixes it? If it does, then re-enable them one-by-one to find which one the clash is with. * David Viewing 7 replies - 1 through 7 (of 7 total) The topic ‘Cloud files authentication error on rackspace’ is closed to new replies. * ![](https://ps.w.org/updraftplus/assets/icon-256x256.jpg?rev=1686200) * [UpdraftPlus: WP Backup & Migration Plugin](https://wordpress.org/plugins/updraftplus/) * [Frequently Asked Questions](https://wordpress.org/plugins/updraftplus/#faq) * [Support Threads](https://wordpress.org/support/plugin/updraftplus/) * [Active Topics](https://wordpress.org/support/plugin/updraftplus/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/updraftplus/unresolved/) * [Reviews](https://wordpress.org/support/plugin/updraftplus/reviews/) * 7 replies * 2 participants * Last reply from: [David Anderson / Team Updraft](https://wordpress.org/support/users/davidanderson/) * Last activity: [12 years, 9 months ago](https://wordpress.org/support/topic/cloud-files-authentication-error-on-rackspace/#post-3866588) * Status: not resolved
