Federation via FederationID between two Nextcloud servers not working

Nextcloud version: 29.0.2
Operating system and version : Debian 12 bookworm
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.59
PHP version : PHP 8.3 (FPM) (mpm_event)

Hello,

I cannot get federation via federation-id running. I have multiple NC server, all fresh install. Sharing by mail, link or to users on same server works without problems. Sharing using FederationID ist not possible. After accepting the remote share by destination- user no new folder or files show up. “Pending shares” and “Shared with you” remains empty. On source site activitys show “user@dst-server.fqdn” accepted the share.
This problem occurs between different vhosts on same Apache server and between vhosts on separate Apache servers.

Is this the first time you’ve seen this error?: Y

Steps to replicate it:

  1. On Source- Site create user “FederationSrc”
  2. On Destination- Site create user “FederationDst”
  3. On Source- Site log on as “FederationSrc”, create folder, create text file in folder
  4. On Source- Site create new share on folder, using FederationID: “FederationDst@dst-server.fqdn”
  5. On Destination- Site log on ad “FederationDst”
  6. On Destination- Site bell shows new notification for new remote share. No “Pending Share” entries will be shown.
  7. On Destination- Site accept remote share (“OK”). Notification empties, but no folder appears. “Pending shares” and “Shared with you” keeps empty.

In nextcloud.log- files I cannot find errors.

I’m also trying to get federation working.

I think mine show up in the notifications. However, when I accept them, they don’t show up in the filesystem.

At one point I got one to work shared from NC28 to NC29, but I’m not quite sure what made that work at this point. Maybe I need to try again. Most of my attempts are between NC29 servers, which are located on my local network.

Regarding the Undefined array key 1 at Cache #41, I get that as well, and created a patch so that it doesn’t show up. (The code there seems brittle.) However, I’m not entirely sure what it’s trying to parse and whether my patch helps. (I just allow it to use the full string if it can’t find the scheme.)

A update after upgrading NC to 29.0.3:

Things becoming a little better:
Shares from external NC are now visible under “Shared with you” after accepting. Also pending shares are visible.

But: Federation is still not working. :frowning:
External shares do not appear under “files”. If clicked under “Shared with you” the view simply switches to files root (“All files”).
