Hi Hasan,
Could you try by adding this configuration:
// Arbitrary identifier of this Orthanc server when storing its
// global properties if a custom index plugin is used. This
// identifier is only useful in the case of multiple
// readers/writers, in order to avoid collisions between multiple
// Orthanc servers. If unset, this identifier is taken as a SHA-1
// hash derived from the MAC addresses of the network interfaces,
// and from the AET and TCP ports used by Orthanc. Manually setting
// this option is needed in Docker/Kubernetes environments. (new in
// Orthanc 1.9.2)
"DatabaseServerIdentifier" : "Orthanc1",
Between reboots, when containers are recreated, they might receive different MAC addresses and therefore might not “find” the server properties that have been written during a previous execution.
HTH,
Alain.
