From the /var/log/vmware/vsphere-ui/logs/vsphere_client_virgo.log

com.vmware.vapi.std.errors.service.unavailable => {data=<unset>,error_type=SERVICE_UNAVAILABLE, messages=User session count is limited to 550. Existing session count is 550 for user <Username>., localized=<unset>, id=com.vmware.vapi.endpoint.failedToLoginMaxUserSessionCountReached,

Environment

VMware vCenter Server 7.0.x
VMware vCenter Server 8.0.x
Site Recovery Manager 8.x
VMware Live Site Recovery 9.x

Cause

This issue occurs when the user session count maximum is reached on the vCenter Server.

Resolution

To address the issue, follow below steps :

IMPORTANT NOTE: Make sure that we take appropriate snapshots of the vCenter prior to any modification.

1. Reboot the affected vCenter Server.

2. Increase the session.maxSessionsPerUser value on the affected vCenter.

Please follow the KB to make the necessary changes under "session.maxSessionsPerUser value"

"User session count is limited to 550. Existing session count is 550 for user" during SDDC Manager upgrade precheck or Lifecycle Manager

3. Reconfigure the VLSR appliance 

Additional Information

Restarting the vCenter server may momentarily help in reconfiguring the VLSR but recomended to increase the session.maxSessionsPerUser value
