I'm having issues with my portal enterprise 10.6 setup.
I have a feature service which was created using Survey123. It all worked fine but one day all attachments have gone missing and if I checked the logs I would get the following:
I exported the Feature service as an FGDB and it all looks fine inside a GDB.
I would just remake the service and move the data but I had this issue in the past and I would like to find a solution rather than a workaround.
