• Cashiering
• SQL
• Database

Cashiering services and application pools are not able to connect the SQL database. The root cause is typically due to a hung connection, blocked firewall ports, a full drive or an invalid database connection string. 

OnPrem Clients:

1. Log into the Cashiering application server (typically the infrastructure server) with tylerservice or equivalent
2. Confirm disk space is not the issue. 
   1. Open File Explorer > This PC 
   2. Note: If the drive listed on the event viewer error is full, clear disk space using the applicable server section from this article Clearing Disk Space On A Munis Server

   4. If the worker service stays running, open IIS and recycle the Cashiering application pools (Ex: prod.cashiering.xxx)
4. If the worker service stops immediately, the service may not be able to connect to the database
   1. Check that SQL services on database server are running
   2. Check firewall requirements, particularly on the database server: Enterprise ERP Port and Firewall Requirements
