[Bug]: Links to other nextcloud instances (ocm_provider) which are not reachable (connection timeout) slow down webdav #42027

Closed suchwerk closed 7 hours ago

suchwerk commented 11 months ago

Bug description

Opening a shared link (not related to the ocm-provider that's connection is broken) is very slow (took 10s to open a directory). After investigating i saw in the logs that there are timeouts on a ocm-provider in the (exactly) same time range. After removing this link the webdav's behavior was normal again.

GuzzleHttp\Exception\ConnectException: cURL error 28: Connection timed out after 10000 milliseconds (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://cloud.xxxxx.xx/ocm-provider/

In the UI there is no information that this ocm-provider is not working correctly. Only if you look at the detail pages. Maybe a hint on link level would be good.

Steps to reproduce

  1. Create link to a ocm-provider that produces a timeout
  2. Generate a shared link
  3. Open that link

Expected behavior

Normal reactivity of webdav access on broken ocm-providers

I experience the same behaviour, resulting in WebDAV-enabled clients timing out, etc.

Figured out I've one federated share, which is currently down. For your situation that would be the "remote":"https://cloud.xxxxx-xxxxxxn.de".

Could you verify if this "remote nextcloud" instance is still accessible?

Besides this cause, it would be nice if this error is reflected somewhere, or temporarily disable the remote/federated share after some attempts.

Why is this causing a delay for a WebDAV call directly to a specific file, which is just locally in the root dir?

`curl --user ':' 'https://nextcloud./remote.php/dav/files//' took around 11 seconds.

apoger commented 10 months ago

I am also affected. The message "OCMProviderException" stays after deleting that specific OCM share from the admin sharing panel. Strange!

zulf10 commented 9 months ago

Same problem.

Also on users pages on url: /ocs/v2.php/cloud/users/details?offset=0&limit=25&search= with message "cURL error 28: Connection timed out after 10000 milliseconds (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://nextcloud/ocm-provider/"

I have a Caddy proxy (On Proxmox LXC) that refers to a Nginx+php-fpm (On Proxmox Debian VM) in same local network. All supply chain can ping an curl nextcloud address

All apps are slow (10s to 15s per actions).

I have increase timeout on Nginx and php-fpm but same issue.

Is anything to do ?

In my case, a physical firewall is present upstream of the host server (in addition to the host and VM firewalls). It was the physical firewall that prevented the VM's Nextcloud from polling itself. By adding a LAN => LAN rule, the Nextcloud is able to resolve its own domain.

Is it any clearer?

gerion0 commented 2 months ago

I have the same problem:

  1. I once made a federated share to a nextcloud instance behind a dyndns domain.
  2. The domain is long gone.
  3. My nextcloud tries to keep to connect to that instance (slows down and spams the log).

My questions here:

  1. Is there a way to "unshare" the folder in the webinterface? I'm not even knowing anymore the shared folder's name. Is it possible to find out the local path in my instance to the respective shared folder?
  2. Is there a workaround by deleting the required database rows? Which table stores the information for federed shares?
