Why does my deployed view only client process stop when trying to obtain network view only licence from primary server?

When I start a deployed 2020R2 update 10 view only client, the runtime manager shows a "client process" stopped error. The client should get a view only licence from the primary server. Licences are in support to v8.50 and 21 are available from the primary server usb dongle.

Syslog of client reports licence expired and sentinel cannot supply a licence:
