Are you using external storage, if yes which one: no
Are you using encryption: no

Are you using an external user-backend, if yes which one: no

I tried to fix .htaccess file with manual update and with the occ command to generate a new one but I'm not sure it had something to do with that.
I've already open topic on help.nextcloud.com : https://help.nextcloud.com/t/nextcloud-15-update-well-known-webfinger-impossible-to-reach/43082

I'm not alone in this case like you can see in the topic, I don't think it is a big issue but I report it anyway.

Sorry for bad enslish, not my native language.

One issue mentioned there is that /.well-known/webfinger returns "missing resource", but that's working as intended (and means that you need to add an argument):

Try https://your.host/.well-known/webfinger?resource=acct :[email protected], which should return a json document pointing to /apps/social/@user.

No if the app is disabled or absent the error is displayed. The error goes if I activate Social App.
The reporting is about the bad displaying, if the app is gone we should'nt have any error linked to the app. Do you understand the point ? The error doesnt concern directly a redirection issue, what I thought in the beggining, it is about the displaying of error about an app I've uninstalled. If I install back social there will be no error in my overview.

@daita I think the issue here is that if the social app is not enabled, the webfinger endpoint returns an Internal Server Error, which is considered by the setup check as setup wrongly. Maybe we should just don't throw an error of no app hooks into the webfinger?

juliushaertl on 18 Dec 2018

@juliushaertl I guess you're talking about
https://github.com/nextcloud/server/blob/f64bd62f8e438fe36a6c070ac445a07ad22439e4/public.php#L71

that should be changed to

if (!\OC::$server->getAppManager()->isInstalled($app)) {
{
http_response_code(404);
exit;
}

This still gives an error for me in 15.0.4 when the social app is disabled.

I am assuming this is a gui glitch rather than any issue or exposure relating to the config?

mannp on 7 Feb 2019

This seems to still be an issue. Running 15.0.8 on Debian 9 Stretch. I installed Social, never commented out the line in the nginx conf file, and uninstalled Social, and now I see the warning in the settings saying I need to enable it.

@MorrisJobke : We need a strategy in here.

right now, the public.php does not returns if there is no settings core/public_ or if the value of the settings point to an app that is not enable anymore.

Is it a way to execute some code when your app is disabled ? So the social app could reset the settings.

If not, we can:

set the same error code if the app linked to a public interface is not available.
or provide the occ command to the admin to reset the setting.

It’s been 2 months and since this issue has closed, please don’t let this stall. There is no long term or sustainable solution to this yet, as I see it.

@msberends https://github.com/nextcloud/server/pull/16997 does not work for you?

kesselb on 28 Sep 2019

Sure, for the social app it does. But is it sustainable? I.e. is the solution app UNspecific enough?

msberends on 28 Sep 2019

Doesn't work for me and still have the problem.

Stopped trying apps on both my servers due to the lack of support to resolve issues like this for the early adopters.

@daita I don't know :man_shrugging:
