Below is the error logs we found during the connectivity issue. Error log "2018-09-05 19:01:51,019 [56] ERROR Instrumentation.Logging.Logger AX Microsoft.Dynamics.BusinessConnectorNet.LogonFailedException: You are not a recognized user of Microsoft Dynamics AX. Contact your system administrator for help."

On the server with the business connector installed, locate the hosts file (C:\Windows\System32\drivers\etc) and add the IP address of the AOS server which the business connector is pointing to.

I had a similar problem back in the days where my .Net web application from time to time lost the connection to the AOS.
