Are you using Federations / remote shares at all?

The warning is meant to indicate apps that need to be optimized (#46004). The CloudFederationAPI\Capablities class did recently get some changes in v31 via #45979.

I have the same issue as @mhzawadi with 30.0.7. The times are longer (such as 3s), and it's not a warning, it's usually "fatal" (note that the servers are very slow). I haven't heard any screams from the users however. Maybe it should be downgraded to warning even for the longer times.

There's the same issue in a forum thread, but without any response: https://help.nextcloud.com/t/capabilities-of-oca-cloudfederationapi/219467

[joshtrichards]

To any of you reporting this:

Are you using Federations / remote shares at all?

[mhzawadi]

To any of you reporting this:

Are you using Federations / remote shares at all?

None, deleted all remote server trusts

[aptiko]

No federations or remote shares here.

[piratenpanda]

none here as well and seeing the same error

[mhzawadi]

not sure this helps, but I have a log file from this morning
