Site Recovery Manager UI error - Unknown error

Products

• VMware Live Recovery

Issue/Introduction

Symptoms:

• Event message on the Site Recovery UI page on the vCenter: "Site Recovery Manager UI error - Unknown error and The latest version of Site Recovery UI is not available.  Some functionality might be limited":
  

• Event messaging started appearing after upgrading the vSphere replication and site recover manager appliance to version 9.0.2.2

Environment

• vSphere replication version 9.0.2.2

• Site Recovery Manager version 9.0.2.2

Cause

• The IP address in the Certificate had an incorrect IP address which causes the certificate to fail.

• From the vmware-dr.log, we see DNS lookup failed alerts: 
  --> (dr.fault.SitePairingFault) {
-->    faultCause = (dr.fault.DnsLookupFault) {
-->       faultCause = (vmodl.MethodFault) null,
-->       faultMessage = <unset>,
-->       address = "#####",
-->       port = "443",
-->       errorDescription = "DNS lookup failed."
-->       msg = "Failed to look up the host name '####' in DNS."
-->    },
-->    faultMessage = <unset>,
-->    name = "####",
-->    uuid = "####"
-->    msg = "Received SOAP response fault from [<SSL(<io_obj p:####, h:63, <TCP '####: 40416'>, <TCP '####: 443'>>), /drserver/vcdr/vmomi/sdk>]: remoteRecon>
--> SRM server '####' cannot complete a pair operation. Failed to look up the host name '####' in DNS."
--> }

Resolution

• Permanent fix is to create a new certificate that contains the correct DNS and IP addresses.

• Temporary work around - Change Site Recovery Manager and Replication Manager IP/DNS pointers to FQDN.
