Hangfire workers stoped handling job suddenly

I am using Hangfire with Postgres SQL and dotnet core 7. there are 2 window 10 servers running the code as exe files. not in the IIS.

All of a sudden the jobs stopped running they are piling up in the q but looks like not any of the workers handling the jobs.

The first time happened while 2 job was running… other jobs started piling up and assuming there were problems with the workers hangfire did not handle any new job even weirder it did not finish running jobs either.

to fix this I cleared the hangfire tables. updated all the Nuget packages but nothing seems to work.
also, there is no error in the console log either if there is a way to log errors please let me know…

please help me sort this out…
