I'm not using myQNAPcloud, but I am having problems with Qsync (to an NAS with a fixed IP address). So, I hope this is the appropriate place to ask this question. (Kindly let me know if I should ask this in another forum.)
About a couple of weeks ago, I had Qsync set up on a Windows 10 machine and everything worked right out of the box. I didn't use the computer for a while and when I finally did log in, it failed to synchronise. I got an error message about the "Qnap device database has crashed". It asked me to restart the NAS, which I did. But that didn't work.
When I attempt to log in at the "Welcome to Qsync" screen, I hit "Apply" and I get a red "Login failure" message at the bottom. I believe I am being authenticated because if I change my username to some non-existent account, I get a message that says "Incorrect username or password". So, this makes me think that both the username and password are correct, but there is some other reason for login failure.
The same username and password allows me to log into the system on port 8080 as well as FileStation. Meanwhile, I can ssh into the NAS. I read somewhere that removing the /homes/<some user>/.Qsync/ directory is worth trying in order to "reset" things. I gave that a try and no success. However, after the "Login failure" message, the .Qsync directory gets recreated. This is also why I think that I'm being authenticated.
I've turned on the system logs to log various protocols. (I'm not sure which one(s) I should select for Qsync, though.) Anyway, no entry is added to the system logs.
So, I'm a bit lost. The only thing that has happened since when I got Qsync working and when it failed is that I did two upgrades of the firmware. It's now on the latest version.
Here are further details about my system:
- Model name: TS-419P II
- Firmware version and Build Number: 4.2.2 Build 20160901
- Operation System (OS): Windows 10 (but it also didn't work on a Mac)
- OS Language: English
- Number of HDDs: 4
- HDD model: Western Digital
- HDD capacity: 3 TB each
- RAID configuration: RAID-5
- Services enabled: File Station, Qsync, Rsync Server, Apple Networking, Download Station, ftp, syslog, microsoft networking, multimedia management, photo station
- External devices: None
- NAS connection speed/ MTU (found in Network Settings>TCP/IP page)
In addition, the Qsync version is the "latest" -- I just tried again by downloading the latest version from a couple of days ago.
If someone could give me some useful advice, I'd really appreciate it!
PS: I think it is unrelated, but when I ssh in and do a "df", I get this error message "df: /share/external/Etron xHCI Host Controller: Protocol error". But Qsync was failing before I got this error message, so I'm treating this as two separate problems. I'm trying to read up on this latest problem now.
