Azure Site Recovery : On-Prem to Azure vis Site-to-Site VPN

Hi,

I have Site-to-Site VPN betweem Azure & On-Prem. In Azure, I have one Resource Group in which I have one VNET 10.0.0.0/8.This VNET is further divided into four subnets out of which one subnet is used for Azure site recovery in which  replicated VM will resides & get IP from this subnet during failover.
I have Windows 2012 R2 DC without VMM & my guest OS is Windows 7 which is running on it.
My Site-to-Site VPN is working fine. I have configured Azure site recovery & I see Hyper-V host is green under Hyper-V site in ASR. But when I go to my on-prem server, I see guest-os VM is in crtical state & 0% synchronize. I use the storage account in Azure & I allow all the subnets just in case but still its in critical state.
I delete the site-recovery-valult in Azure & remove/uninstalled any ASR related service/software from my on-prem server. I created new site-recovery-vault with different name & now I trying to add again the same server. I downloaded the Azure Site Recovery Installer & new Vault key on my on-prem server but get enclosed  error:





I have went through all Microsoft blogs for ASR & done everything right from GUI to CLI script with multiple reboots of server but no luck.

Earlier I was one step behind & now I am two step behind.
I will be glad if someone from Microsoft team can guide step-by-step here (for my scenario only. I have read Microsoft ASR doc but no luck).

I am in free trial mode now so cant open ticket but will go paid if solution works in lab environment.
