Desktop Client - Connection Closed

hosting

#1

I get the message "Connection Closed" when I try and connect my desktop client.

The URL appears to be OK and I have added additional trusted domains and even set an app password through the web UI but still get this message.

Any thoughts...?


#2

No-one available to help on this...?


#3

Open the client-log-windows with F12. Is the connection closed from server or client?

Possible server-side problems:
The web-interface works properly? Direct access via webdav as well (check with cyberduck, WinSCP)? Check the server logfiles for errors.

If it is the client:

Thanks tflidd

I've restored the owncloud repository to a version I KNEW worked and has all the files etc needed. I can easily access the web interface and there's no issues sharing files etc.

However, despite uninstalling and re-installing the desktop client it simply will not connect. I tried accessing the the client log but as it has been re-installed it simply brings up the connection dialog:

I checked the web log and no entries at all for today.


#5

I checked the client log on my laptop as this has not been re-installed and it was empty. Grrr...


#6

An update, from the client on my laptop:

Maybe you need to have a look at your webserver and its configuration rather then the client?


#8

Thanks Tom, that's exactly what I'm doing today actually.

As we run a dedicated server it'll be easy to make any changes required but the only thing I can think of that might possibly have had an effect was that we deployed HTTP2 a few days ago.

We reinstalled OwnCloud client and even rolled back the web app to a version prior to the problem and still no connection on Desktop either from the tower or laptop or even on Android so I suspect it may well be HTTP2 that's causing the issue.

Or maybe something else.

If I find out what I'll be sure to post though, thanks.


#9

I was just clicking around in the documentation and found the following docs: https://doc.owncloud.org/server/latest/admin_manual/issues/general_troubleshooting.html#common-problems-error-messages Maybe this also gives a few additional info.


#10

Thanks Tom

I had a read through that,m changed the Keep-Alive setting and yes it took longer but still closed the connection.

I suspect it's a firewall setting on the server but ConfigServer Security & Firewall blocks based on IP addresses, not applications. I even disabled the firewall but still no joy.

The log output from the laptop client (completely unchanged throughout this whole process) simply shows that it is repeatedly trying to connect.


#11

The posted link is explaining something about an Apache module. Maybe this got changed by the move to HTTP2? Or this HTTP2 is generally not that stable or buggy in Apache?


#12

I thought the same so I disabled HTTP2 but still no connection. PITA I know.


#13

Or try the demo setup to connect the client. This way, you can find out if the problem is on client side (firewall etc.).


#14

Thanks, I tried that and it worked OK which is why I am focused on the web side of things.

Ideally a list of what OwnCloud DOES NOT support would be nice so I can walk through it but I can't seem to find such a list.


#15

I have since completely re-installed OwnCloud on our server and still am unable to login using the desktop client.

I do however have a client on the laptop where the credentials remain unchanged but get this in the desktop client log on the laptop:

#16

I think if the issue is somewhere within PHP or your web server configuration re-installing ownCloud won't help. Maybe you can try to open https://cloud.MyCloudDomain.co.uk/remote.php/webdav to see if a basic connection to this is working?


#17

I would have agreed with you but yesterday I tried to connect the Android app and got invalid username and password.

I re-installed the app, setup a new admin login through the web UI and got the same error.


#18

I think this is exactly confirming what i'm always trying to say: The issue is somewhere within your server configuration / environment, not within your clients.


#19

I'm not disagreeing but I have been trying to solve this for weeks now and no help.


#20

Still having the same issue despite numerous uninstalls and re-installs. I've even tried a spare domain we have and the same issues.

Any thoughts...?

From the client app all I get is connection closed whether I use http or https

I have added both the www and non www domain to the config and redirected to the non secure http.

Any thoughts...?
