For maintainers, I am the user the OP is attempting to supply a share to. We both run separate servers on separate domains. We are both running 18.0.4 stable.

I am seeing this issue as well, though in my case, the two servers are running different versions of Nextcloud: 18.0.6 (offering share) vs 19.0.0 (accepting share).

It appears the POST is blocked by CSP. Some additional info from the console:

Content Security Policy: The page's settings blocked the loading of a resource at http://{{ URL_OF_ACCEPTING_SERVER }}/ocs/v2.php/apps/files_sharing/api/v1/remote_shares/pending/2 ("connect-src"). xhr.js:178:12

In troubleshooting other issues related to the same cause, I was able to find a resolution by modifying config/config.php to contain:

'overwrite.cli.url' => 'https://{{ url }}', # Note the change from 'http' to 'https' here
'overwriteprotocol' => 'https',

This corrects the CSP block from the browser, and federation was able to work successfully.

I can confirm that this problem exists. Receiving server is running version 19.0.3 (docker with nginx reverse proxy), sending server is version 19.0.3 (directly on a Ubuntu 18.04 host, running PHP-FPM behind nginx).

However, setting the overwriteprotocol did not change the generated URL. Can anyone help out here?

I looked at #14132 which is similar but regarding the .htaccess values which won’t help out here.

Is this Issue still valid in NC21.0.2? If not, please close this issue. Thanks! :)
