3 Services Disconnected after reboot

awhitfield — Mon, 26 Jan 2026 18:19:17 GMT

Hi Folks,

great way to start a Friday.

Just had a call from a client who have rebooted the QV server earlier today as is now getting:

All service are up and running, they use a domain account as the service user. We have advised them to restart the services but to no avail.

I suspect this may be a DNS issue:

I have seen other threads that recommend changing to use Local host, but do you actually change it against the Qlikview Server Name e.g

and the same place against the other services?

Any suggestions please!!

Cheers Andy

Or do you change it in the URL ?

"Disconnected" usually means that accounts, permissions, or network connections have changed. When a service reports a "Disconnected" status, the real explanation of the problem is detailed in the corresponding log file.

It would be nice if we could take a peek in those three QlikView service log files...

Best,

Peter

BTW it's funny that the services are running on one server (first screenshot), but the configuration talks about another server (last screenshot, bottom field called "URL")...

Is your customer running a cluster, or trying to configure one?

Ha ha, the second URL is a screen shot from my PC, well spotted though

Hey Andrew,

Hmmm. Could be a DNS issue. Have you tried substituting IP address instead of servername in the URLs for each of the disconnected services? So, for example, for DSC, in QMC, navigate to System > Setup > Directory Service Connectors > DSC@ > General tab > URL.

Hope this helps

Hi Chip,

not yet, I am just awaiting the log files to come back from the client.

Hi Peter / Chip

Please see log files in attached zip, I'm struggling to spot anything helpful in them...

Andrew,

Need the Management Service logs as well.

Chip is right. QMS is the one reporting problems.

However, the DSC log tells a good story. Apparently there appears to be a problem when trying to reach the domain controller (or LDAP server if that's what your client is using) If accounts are defined on server LDAP://bunzl.internal and that one cannot be reached, in an AD landscape all sorts of things start going wrong...

Maybe a track to investigate?

The most glaring error from QMS log is

Error

System.Exception: Failed to retrieve document list from the specified QVS || at QMSBackendCore.Service.ServiceImpl.<>c__DisplayClass244.<GetUserDocumentList>b__243() || at SolutionGlobal.Collections.ThreadSafeCache`2.CacheItem`1.GetObject() || at SolutionGlobal.Collections.ThreadSafeCache`2.Get(TKey key, Func`1 createObjectFunc) || at QMSBackendCore.Service.ServiceImpl.GetUserDocumentList(Guid qvsID) || at QMSBackendCore.Service.ServiceImpl.Diagnostics.CacheDocumentAvailable()

Typically when I have run into this error, communication between QVS and the Root Folder/Mounted Folders has been interrupted. I believe this lends credence to your original suspicion of a DNS issue.

So everything was working fine yesterday and then all of a sudden the services are showing as disconnected? As Peter mentioned previously, the "Disconnected" error typically refers to accounts/permissions or network issues. How are the different QV services authenticated - via Windows security groups or certificates? If Windows security groups would check for password changes or permissions. If certificates, ensure that the certificate hasn't expired. If all of these are good, then investigate potential network issues. Would start with DNS as I previously mentioned.

Hi Chip,

the Disconnected issue manifested itself after a server reboot on Friday morning.

We advised the client to change to URL to IP rather than Machine name, not heard back yet.

Intend to advise changing the Services user to a local account in Qlikview Administrator and Local Administrators groups,...

Hi Guys,

Just done the following:

Updated the Lef Details – just to be sure as they were showing end date of 2017-09-29
Change the Service logon user to a different domain user with the correct permissions – and restarted the services
Delete the user name and password help against LDAP against the Active Directory option, this isn’t required when the service user is a domain user and appeared to have an incorrect password.
Everything is now up and running

The issue appears to be a corrupted profile on the service user account, would recommend that you create a new Domain user to run the services as a member of local administrators and Qlikview Administrators

Yippee, thanks for the pointers guys!

Happy Andy
