Thanks for the log! It shows that the client regularly runs a CheckServerJob which comes back with RemoteHostClosedError. It doesn't look like a client error... I'll try to reproduce it.

Hm, I can't suspend or hibernate my Windows VM, someone else will need to try to reproduce this.

Note: when i close the client (Exit) and start it again it works! So i think it might be a client bug. I also was checking the owncloud.log. No specific errors in there.

Maybe dicannect from network and reconnect after some time could simulate it in the vm?

@MegaV0lt Disconnecting and reconnecting the network works fine.

The errormessage is differnet, but i think the same reason. The connection is to local server "sheevaplug"... Again, after restart of client ok. Nothing in owncloud.log

From the logs, as ckamm already said: the client is querying to status.php to know if the server is there. But we get an error ( NetworkError::RemoteHostClosedError )

That's strange. Why would the server closes new connections after we resume from sleep? And why would it work again when one restart the client.

the owncloud.log on teh server does not show any access at the time... maybe the request did not even leave the clientpc? Othe rnetworking apps still work normal at the same time (eg. dropbox, ff, tb, webradio). Must be something with the client in my poor opinion

As expected: Nothing after 15 minutes...

Sharing is also not working, because of teh no connection problem, so it is a dropbox-link

The logfile shows this lines:

03-04 17:10:40:698 0x59ee6a0 OCC::Folder::slotRunEtagJob: * Trying to check "ownCloud" for changes via ETag check. (time since last sync: 2271 s)
03-04 17:10:40:699 0x59ee6a0 OCC::Folder::slotRunEtagJob: Not syncing.  : "ownCloud" false "NetworkError"

That means that we do NOT start the ETag job because the AccountState is Network Error rather than Connected.

And other lines:

03-04 17:11:36:420 0x59ee6a0 OCC::AbstractNetworkJob::start: !!! OCC::CheckServerJob created for  QUrl( "https://sheevaplug/owncloud" )  querying "status.php"
03-04 17:11:36:441 0x59ee6a0 OCC::AbstractNetworkJob::slotFinished: void OCC::AbstractNetworkJob::slotFinished() 2 "Verbindung beendet"

In the normal case, a succeeding CheckServerJob would reset the AccountState to Connected, and as a result the ETagJob from above would start. The CheckServerJob is actually started, but it fails reporting "Verbindung beendet". This job just tries to access status.php. Is it possible that there is any problem in your setup causing this?

What should this be? I have a local network-connection with the oc-server (sheevaplug). I use my self created ssl-certs. On my laptop is still version 1.7 of the client but usese dyndns as adress of course

Windows: Reset QNAM as a workaround. owncloud#2899 owncloud#2895 ownc…

The QNetworkAccessManager is reset when we are disconnected, just
before attempting to fetch the server's status.php.

This may help fix the problem described in various issues where we
get 'Connection closed' or timeout errors after the OS has woken
from sleep.

@MegaV0lt I just pushed a possible workaround. Could you try again with tomorrow's build from http://download.owncloud.com/desktop/daily/ ?

@MegaV0lt Any news? Your symptoms looked identical to the ones in #2973 and there the patch seems to have helped.
