• Fresh install on local Synology NAS, with cloudflare tunnel connection. Website resolves and is reachable, but any attempt to change/edit/or publish changes are denied with: “Updating failed. You are probably offline.”. I am not offline. Yes, I have read about REST API that caused this problem with other users but there is no REST API error in the site health section under tools. Additionally, there is a “recommended improvement” indicating “Cannot access filesystem”, “please check credentials”. If I’m already logged into the admin for the wordpress site, how is it that my credentials need checking?

  • This issue is likely related to your WordPress install running behind a Cloudflare tunnel, which can block REST API or HTTP requests that WordPress needs. Even if the REST API looks fine in Site Health, it might still be blocked or not returning properly due to the proxy. Also, the “Cannot access filesystem” warning suggests WordPress can’t write files. try setting proper file permissions on your NAS.
    Check if FS_METHOD is defined in the wp-config.php file. Adding define('FS_METHOD', 'direct'); can help too.

    Some users have indicated that the AI training BOTS may have been blocking the REST API. I have turned that off at cloudflare and this did not help.

    The http user and the database user for WP and the database are defined users in the NAS and they all have full read/write privileges to the root Web folder. Still no change to any of the original problems.

    I tried adding the FS_METHOD you suggested above. This resulted in a 505 error when trying to bring up the site.

    Are there any other suggestions you may offer?
