@Berhinj The issue is with parallel=True. The following works as expected:

```python import fsspec import xarray as xr paths = [ 's3://noaa-goes16/ABI-L2-LSTC/2022/185/03/OR_ABI-L2-LSTC-M6_G16_s20221850301180_e20221850303553_c20221850305091.nc', 's3://noaa-goes16/ABI-L2-LSTC/2022/185/02/OR_ABI-L2-LSTC-M6_G16_s20221850201180_e20221850203553_c20221850205142.nc' ]

fs = fsspec.filesystem('s3', anon=True) flist = [fs.open(path, mode="rb") for path in paths]

single dataset

ds = xr.open_dataset(flist[0], engine="h5netcdf") print(ds)

multiple datasets, ATT: parallel=False works

ts = xr.open_mfdataset( flist, engine="h5netcdf", combine="nested", concat_dim="t", parallel=False ) print(ts) ```

I've not digged further, but it looks like it has some issues with the file-object...
