Network share backup failure with timeout error


My UrBackup server version is 2.0.38
UrBackup server OS: CentOS 7

Tried to install UrBackup client package on W2K12 OS, but urbackup client application is crashing with ntdll.dll error. Have update the OS but still the same issue.
W2k12 is my file server and i have to take backup of it. so i have installed urbackup client 1.4.11 on my personal laptop so that i can configure the file server data backup as network share backup.
I have configured the network share backup \<share>\ and backup starts fine. But i have more than 300GB data in my file server and while creating filelist backup fails with timeout error.

Dear UrBackup Team,

When I try to start Image backup after some time it’s getting Timeout error
if you have any other plane to take backup

Please help out regarding this
