Hi Vadmin,

Does the error have any impact on your Nextcloud for any of your users?

Should there be a folder called nextcloud404 under /var/www/ ?

To me this looks like someone or some script tried accessing this path but it doesn’t exist.

[Vadmin]

I checked my nextcloud config and unfortunately did not find any errors there. I have Ubuntu installed on 04/18/03, today an update has taken place, and it seems after it all started.
If you add the line to the config: if ($uri !~* (?:.(?:css|js|svg|gif|png|html|ttf|woff)$|^/(?:remote|public|cron|status|ocs/v1|ocs/v2).php|^/.well-known/acme-challenge/.*$)){
rewrite ^ /index.php last;
}
That everything works. But I don’t understand what this line is?
Yes, and the error affects, because I have lost the icons in the web interface of my Nextcloud

@Vadmin

I have Ubuntu installed on 04/18/03, today an update has taken place, and it seems after it all started.

So you have Ubuntu installed and today you updated Ubuntu and since the update of Ubuntu you are experiencing this problem? Or was it a Nextcloud update which is causing this issue now?

@Vadmin

If you add the line to the config: if ($uri !~* (?:.(?:css|js|svg|gif|png|html|ttf|woff)$|^/(?:remote|public|cron|status|ocs/v1|ocs/v2).php|^/.well-known/acme-challenge/.*$)){
rewrite ^ /index.php last;
}

In what config did you add this? Was it the config/config.php or did you add this to the htdocs/.htaccess ?

@Vadmin

Yes, and the error affects, because I have lost the icons in the web interface of my Nextcloud

Do you mean the avatars of the users or all icons, such as folders, etc. ?

I have had a look on Github and found this issue, which looks similar to your error in your last reply.

[Vadmin]

@CFelix

Итак, у вас установлена ​​Ubuntu, и сегодня вы обновили Ubuntu, и после обновления Ubuntu у вас возникла эта проблема? Или это обновление Nextcloud вызывает эту проблему сейчас?

This error appeared after updating Ubuntu. Although this is strange. I did not update nekstklood.

@CFelix

В каком конфиге вы это добавили? Это было config/config.php или вы добавили это в htdocs/.htaccess ?

I added this to the nginx config, that is, not to the most important file, but I have created another nextcloud.conf.
I have a bunch of Ubuntu + Nginx + Php-fpm installed

@CFelix

Вы имеете в виду аватары пользователей или все значки, такие как папки и т. Д.?

Я посмотрел Github и обнаружил эту проблему , которая похожа на вашу ошибку в вашем последнем ответе.

The “search” icons, as well as the “users” are not displayed.
Unfortunately, the mistake that you found on the github does not suit me.

[Vadmin]

And in what file do the values that are indicated change? https://github.com/nextcloud/server/pull/16571/files

[CFelix]

If you updated Ubuntu, there could be a certain package causing your issue. Please could you check your /var/log/apt/history.log to see what has been updated and maybe post it here?

I vaguely remember that someone on the forums had kind of a similar issue. He had done an OS update, which caused his Nextcloud to misbehave. He found out, that it was a PHP package causing it. I’ll have a look and see if I find it again.

The file in question is in htdocs/core/Controller/PreviewController.php of your Nextcloud installation. But if it doesn’t suit you, please refrain from changing it as it could cause more issues than you already have!

[Vadmin]

Unfortunately, the logs were not preserved.
I will try to change my config, in accordance with the official https://docs.nextcloud.com/server/13/admin_manual/installation/nginx.html it is possible that somewhere there was originally an error, but everything worked.

[CFelix]

Who knows, maybe you’re right about the config Try it (make a backup before though ) and see how it goes.

Waiting for your reply.

[Vadmin]

Thank you very much for your help. As soon as I make the correct configuration and check, I’ll write right away.)
