Servers in hangfire "Servers" section disappear unexpectedly

I have hangfire service (site/URL) consist of 3 servers. It has been run perfect on windows server 2012R2 (on IIS). We have migrated these servers to Windows server 2022. Since then, Servers in hangfire “Servers” section disappear periodically while actual IIS services in those servers are up and running.

When it happens, we need to recycle the IIS AppPool to get the server visible under the “Servers” in hangfire. Nothing on event logs can be found.

Any suggestion for what should be checked further?
