Here is my log from the Windows Sync app

Installed latest Windows app. Fresh install of Owncloud 9.1.0. Working ok. But when I try to use the Windows Sync program it doesn't sync properly and gives me errors that I have no idea are. Is there anyone that can understand this?

Please check the server logfiles why there is an error 503. How did you install owncloud (packet manager, manually)?

I extracted all the Owncloud files in the main public_html folder and then just brought up the web page in a browser which let me configure the first account and input the DB information.

Still this is valid:

Without any logentries from the server this is just guessing game...

Here is what is in my log...

I see the 503 errors but no information about anything. I also disabled my firewall in case that was it. I also opened a ticket with my ISP that hosts the VPS. Something is not turned on or something somewhere.

Those are the access logs which never shows enough info. See the other logfiles like described here: https://central.owncloud.org/t/how-to-find-webserver-or-oc-logfile-enable-php-logfile/808

This is btw. also asked in the template prefilled when creating a new thread here. Nearly every info is currently missing about your environment.

Sorry about not inputting the specs on the server. I will.

The system is CentOS 7 64bit. It is a VPS. Has 2GB of memory and plenty of hard drive space. I have root access to the system.Web server is Apache. MySQL is 10. Owncloud v9. Does the Owncloud sync program use WebDAV for transferring the files?

Here is the domain log
https://paste.ee/p/a6Aeu

And here is the error log.
https://paste.ee/p/Gyxh3

Owncloud log itself. Locally.
https://paste.ee/p/hXIjt

And the owncloud-log on the server?

What is strange, you have the 503-error in your access.log (or domain.log) but not in your error.log. Do you use a specific error-log for your domain?

When I try to access using WebDAV via the web browser using a username and password it comes back with, that's what the Owncloud Windows app uses, right? Also, I'm still searching for the server owncloud.log file. Found it.

https://paste.ee/p/T9bjZ

ownCloud

App not installed:
ownCloud – web services under your control

Just to make sure:
{"reqId":"V9slPN-qPf0KBToT9nj1uQAAAAY","remoteAddr":"your-ip","app":"PHP","message":"fopen(\/home\/diggscloud\/public_html\/data\/Michael\/files\/Photos\/Paris.jpg): failed to open stream: No such file or directory at \/home\/diggscloud\/public_html\/lib\/private\/Files\/Storage\/Local.php#273","level":3,"time":"2016-09-15T22:48:29+00:00","method":"GET","url":"\/remote.php\/webdav\/Photos\/Paris.jpg","user":"Michael"}

This file does exist on your file system? And there is no restriction from mod_security or SELinux that prevents access?

No, I have deleted the stock photos that came with it, but used the Owncloud web interface. I didn't remove them with SFTP or anything like that. I can remove the account and re-create it. And if any files were deleted manually, this would be a symptom?

It's ok to delete them via webinterface. Perhaps you deleted them after 2016-09-15T22:48:29+00:00?

I re-created my admin account which put back the stock photos and document file. After I did that I restarted the sync client and it finally synced up without errors. I tested it out by copying files into the local Owncloud folder and the files did populate when looking at the web interface. All this time and looking deep into the logs to find out if you delete files any other way besides the Sync client or web interface you will break the sync client. I'm not sure why this would happen, but Owncloud has some pretty strict and tight processes. I always using some kind of SFTP client, so I need to make sure when dealing with Owncloud DO NOT touch any of the files manually. Maybe one day we will be able to use FTP as the admin to quickly move files to users folders and all that jazz.

Thanks for the help. Next on my list is to figure out how to turn on caching.
