Error: The remote server returned an error: (404) Not Found.

Hello,

We're seeing a large number of Hyper-V VMs have backup failures with the following error:

Error: The remote server returned an error: (404) Not Found.

The Windows event logs aren't giving me any information about this error. It looks like this issue was fixed in a previous version of vRanger (7.6.5). Has anyone seen this error before and been able to pinpoint the cause?

Any help would be appreciated, thanks!

    Hello Alex, 

    This usually is related to the agent timeout when creating the snapshot on the Hyper-V host. We marked it as a defect in the past because the 5 minutes timeout was hard-coded. If you have the Hyper-V agent updated to the vRanger version you are using (usually some customers upgrade vRanger and not the agent), You can modify the timeout to see if it helps:

    On HyperV Host

    Step 1: Login Hyper-V host System and go to "C:\Program Files\Quest\HostService"
    Step 2: Open config file "Quest.Hyper_V.HostService.exe.config"
    Step 3: Increase the timeout value by changing
    <add key="OrphanedSnapshotsTimeOut" value="5"/>
    to
    <add key="OrphanedSnapshotsTimeOut" value="120"/>
    Step 4: Restart Service "Quest Hyper-V Backup Agent"
    Step 5: Start Backup job.

    If this doesn't help, please create an SR so we can investigate this issue. 

    Thanks!
