WMS Pull / Push Images Failed with Error 105

Hi, I´m new to WMS and trying to implement it in our company.

We used devices based on Dell 5470 Mobile with Windows 10 IoT installed, and WMS Server installed on version 1.4 and upgraded to version 2.0.

Device are enrolled by DHCP Option correctly and devices and apps policies applyed without issues.

When i try to Push or Pull images, i got the error :

“userX” initiated ImagePull (url: https://fqdnservername:443/ccm-web/image/pull/Test-Pull, repositoryId: 1, isCaValidationOn: false) on “devicename” at ‎09‎/‎21‎/‎20 ‎7‎:‎29‎:‎15‎ ‎PM (Status: Failed – [ERROR: WMS File Repository Server not found. (error code : 105).][ERROR STAGE: Repository validation.][REASON: Could not connect to repository server.][SOLUTION: Check the network connection/authentication.]| (105))

The server and the devices are not in the same Vlan, does i need to add other DHCP option to allow PXE like option 66 and 67 like Windows Deployment Service or SCCM ?

Thanx.

Take care
