I have a single machine deployment of FMS 15 which I upgraded from FMS 14. Since doing so I am unable to upload files to the server. FMPA simply says that the upload failed. FMS admin console reports an error message: "Redo log(s) for database "Filename" failed to update to the Standby Server. (20402)". I have tried restarting the database server, and restarting the server machine itself. No change. I don't know why it is referencing a "Standby Server" in the error message because I don't have one configured for this deployment. I suspect this is part of the problem but have not had much luck so far in locating information on this error.
