Source server registration to ASR configuration server failed

VJ-8370 441

Hi,

Source server registration with ASR configuration server failed with error "post request: (7) - Couldn't connect to server". Checked that connectivity is there between source server and configuration server on ports 443 and 9443.

Verified the steps documented here - (https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-troubleshoot-configuration-server), but with no luck.

There are other servers which are replicating without any issues.

Can anyone advise what could be the possible reason for this error?

Regards,
VJ

@VJ-8370 Thank you for your post and I appreciate your patience here!

Suggest you to try suggestions from the troubleshooting guide - https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-troubleshoot-configuration-server#process-servermaster-target-are-unable-to-communicate-with-the-configuration-server if not done already.

If this a VMware or Physical to Azure set up, try the following:

To avoid any unexpected issues in future , please try downloading the latest OVA template again from the vault and re-deploy the configuration server. It should contain all the required applications & files. If you still see same error ,reboot the server and cleanup all contents in C:\ProgramData\Microsoft Azure Site Recovery\fingerprints directory.
Then re-register the CS to the vault.

Hi Sadiq,

Thank you for the response. Tried all the troubleshooting steps. Connectivity is available on port 443 from source server to configuration server.

There are many other VMs (which have GBs of data) already replicating via this configurations. During the initial setup ASR has been installed couple of times (clean installation).

Are there any other possible options to get through this issue? Any other troubleshooting to be done?

@VJ-8370 Not that am aware of . But for sure Azure technical support team may have a solution to your issue and that is only possible through a good amount of investigation into the logs.

In short - Please contact Azure technical support team for further investigation into this issue.
