What about adding a link on the message to customclient_desktop link?
This could lead to a better UX after all (upgrade one-click away!) :)

@nextcloud/designers what do you think?

I don't know how to fix the tests. I tried to run it locally:
An unhandled exception has been thrown:
Exception: Environment not properly prepared

I need help.

@camilasan I was more thinking about a clickable link (if it can be done).
Somethiing like:

The current version of Nextcloud Desktop client is not supported by this server (client version 3.11+ is required).`
Go to Nextcloud Downloads page to download the update.

Otherwise, the full link is too much noise IMO :(

[nimishavijay]

Agreed with @solracsf that the link could be hidden. What do you think about adding the link to the text "version 3.0.0 or later"? Would that be possible :)

Unable to connect to Nextcloud.
This version of the client is unsupported. Upgrade to version 3.0.0 or later.

done, please review @solracsf

[solracsf]

Fine by me. 👍
Maybe just update the 1st post with an updated screenshot of the final version.

Seems good if it’s a clickable link like @solracsf suggested. :)

Another detail: In the settings it says "Unable to connect to Nextcloud" and in the notification "Network error" – both of these are different and neither really seem correct for the issue?
Maybe rather it should say "Connection issue" @camilasan?

I changed it here: nextcloud/desktop#6514

since the message reason may vary, I think 'Connection issue' is better.

@jancborchardt I didn't realize your comment only referred to the strings used in the desktop client. So this PR on the server is actually done.
