We moved code to a new target environment, where the Host-Instances didn’t match the source environment. We reconfigured some of the HostInstances to allow for a default 32-bit host instance, then restarted the Host Instances.

Orchestration is being used to send files to a dynamic FTP. We store the FTP site, user, password in a SQL table to allow us send to many different FTP trading partners.


Unenlist and re-start the dynamic send port. Apparently restarting the Host Instances was not enough.

This is the site that helped me resolved it:
