System Information

• OS: 10.0.22631.3007
• BOINC Version: 7.24.1

Additional context
It seems as if response to a request gets lost, and boinc manager remains content to wait for a response infinitely, without timing out.

There is no easy way to do a simple timeout from this situation, as the lost RPC can potentially cause significant problems for the BOINC Manager. But if you click on the Cancel button, the Manager will reset its communications and try to recover.

What happens if you click on the Cancel button?
