Database Connection Issues

Hi all,

New to Blue Prism support so apologies if this is a common issue.

We are experiencing some strange db connection issues.

Error: Could not connect to database 'PA application server'

Connection failed - Exception has been thrown by the targetof an invocation.

System.Reflection.TargetInvocationException: Exception hasbeen thrown by the target of an invocation. --->System.Net.Sockets.SocketException: No connection could be made because thetarget machine actively refused it IP XXX.XXX.XX.XXX

Server stack trace:

We have been experiencing similar issue with our production server. If we do a restart on the runtime resources they then show with the error: 'No connection could be made because the target machine actively refused it IP XXX.XXX.XX.XXX', the resource then continually tries to establish a connection which shows as 'Missing' or 'Lost'. We can only resolve this by remotely logging back onto the runtime resource, the issue only started occurring since last week, until then we had no issues.
