Why is the owncloud client not syncing files (owncloud operation cancelled)?

Question

css

The problem is that the client does not synchronize all the files from the server to the local computer. But only a part.
In client logs

operation cancelled.

In the server logs

Exception: {"Message":"HTTP\/1.1 503 Could not open file","Exception":"Sabre\DAV\Exception\ServiceUnavailable","Code":0,"Trace":"#0 \/var\ /www\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/CorePlugin.php(83): OCA\DAV\Connector\Sabre\File->get()\n#1 [internal function ]: Saber\DAV\CorePlugin->httpGet(Object(Sabre\HTTP\Request), Object(Sabre\HTTP\Response))\n#2 \/var\/www\/owncloud\/3rdparty\/sabre\/ event\/lib\/EventEmitterTrait.php(105): call_user_func_array(Array, Array)\n#3 \/var\/www\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/Server .php(459): Saber\Event\EventEmitter->emit('method:GET', Array)\n#4 \/var\/www\/owncloud\/3rdparty\/sabre\/dav\/lib\/ DAV\/Server.php(248): Saber\DAV\Server->invokeMethod(Object(Sabre\HTTP\Request),Object(Sabre\HTTP\Response))\n#5 \/var\/www\/owncloud\/apps\/dav\/appinfo\/v1\/webdav.php(56): Saber\DAV\Server-> exec()\n#6 \/var\/www\/owncloud\/remote.php(138): require_once('\/var\/www\/ownclo...')\n#7 {main}" ,"File":"\/var\/www\/owncloud\/apps\/dav\/lib\/connector\/sabre\/file.php","Line":306,"User":"owncloud_username" }

Rescan files did not help.

sudo -u www-data /var/www/owncloud/occ files:scan --all

Any more ideas?

.container {
    width: 300px;
    height: 300px;
    background-color: green;

}

.container:after {

    height: 100%;
    vertical-align: middle;
    display: inline-block;
}

.container span {

Horizontally - text-align: center to parent, not on itself
Vertically - set parent's line-height equal to parent's height (works if 1 line and parent's height is known).
