NBU 8.1.2 Media Server communication failure with Master Server following upgrade
we've come across a couple of challenges with our 8.1.2 upgrade. After the master server upgrade we started on the media servers and straight away encountered issues downloading certificates required for communication between the Media and Master Server. The media Servers are configured with a preferred network to backup our client database servers on a separate vLAN. This is where the crux of our issues currently reside: If we disable the preferred network (rename PREFERRED_NETWORK to something else in the registry) clear to host cache communication between master/media server is established and the certificates can be uploaded. After making the certificates available for the media server we then reenable the preferred network and communication is lost again. Running “bpclntcmd -pn” from the media server with the preferred network disabled proves connectivity however running it with the preferred network enabled doesn't provide a response. Additionally, running “bpclntcmd -pn -verbose -debug” from the media server with preferred network enabled throws out the following errors: 13:47:37.508 [7764.9212] <2> check_vnetd_process_dup_permission: OpenProcessToken() failed: 5 13:47:37.508 [7764.9212] <2> vnet_check_windows_privileges: enabled SeDebugPrivilege privilege 13:47:37.524 [7764.9212] <8> init_local_connect_recs: [vnet_connect.c:1398] remote connections are prohibited 2 0x2 13:47:37.524 [7764.9212] <8> init_local_connect_recs: [vnet_connect.c:1398] remote connections are prohibited 1 0x1 13:47:37.524 [7764.9212] <16> connect_to_service: connect failed STATUS (18) CONNECT_FAILED 13:47:37.524 [7764.9212] <16> connect_to_service: JSON data = {"allow_large_status": [TRUNCATED] "connect failed STATUS (18) CONNECT_FAILED"}} 13:47:37.524 [7764.9212] <8> vnet_connect_to_service: [vnet_connect.c:290] connect_to_service() failed 18 0x12 13:47:37.524 [7764.9212] <2> bprd_connect: vnet_connect_to_service(MasterServer)failed: 18 13:47:37.524 [7764.9212] <16> do_request: Can't connect to host MasterServer: cannot connect on socket (25)Can't connect to host MasterServer: cannot connect on socket (25) When running “bptestbpcd -host MediaServer -verbose -debug” from the Master Server (Preferred Network enabled) I get the following: Host MasterServer (ip address) is not an authorized server for host MediaServer. bptestbpcd: EXIT status = 46 server not allowed access The preferred Network settings only contain the client names and IP Addresses of the Database clients, not the media servers or master server. There is no preferred network configured between the master and media servers so I cannot understand why communication is lost when the preferred network settings are in place? I suspect it’s relating to certificates but haven’t as yet found anything online similar to the issues we have. Support have suggested speaking to our Network Team, however they do not know what the issue is. Does anyone have any idea’s?
