We successfully configured a print agent for IFS8 on a windows server and have been using it for several years. Occasionally, it will report that it is unable to connect to the URL of the application server, reporting that it is either not running or is not correctly configured. From that point on, we are unable to print anything from IFS.
The application is running. The only way we have found to get printing working again is to stop and restart the ManagedServer1 process. This is a major interruption to the users because it stops them from using the application.
Does anyone know why IFS printing is reporting it cannot connect to itself?
The full error details follow:
