Security Token Service stops issuing tokens

I'm currently having problems with Security Token Service (STS) on my Sharepoint 2019 server on premise single server.  The STS service stops issuing tokens after the first day of the SharePoint installation.  I'm currently using self certs and receiving the events provided below.  Seems to work fine at first but the STS service will just stop issuing tokens after about a day.  Any suggestions?  Thanks,
