Failure in retrieving content from a backup restored collection created on a different machine

Yes, this is probably some conflict on embedded running on port 6060 for profiling.

Can you try moving away from embedded? This is only meant to allow a quick run on Weaviate directly from the client.

you can copy over your data from the Embedded Weaviate path to the same path at PERSISTENCE_DATA_PATH at a docker instance for example.

Also, have you tried running on a newer client?

Thanks!
