The same code works well for `parallel=False`.

```python
import xarray as xr
import pandas as pd

# list daily timestamps from a starting date to an end date
dts = pd.date_range(start = ""2013-01-01"", end = ""2022-12-01"", freq = ""D"")

# base url for the files
base = ""https://goldsmr5.gesdisc.eosdis.nasa.gov/opendap/MERRA2/M2I3NPASM.5.12.4/""
# prefix of the files
prefix = ""MERRA2_400.inst3_3d_asm_Np""

# function to construct the url of the files
url = lambda d: f""{base}{d.year}/{d.month:02d}/{prefix}.{d.year}{d.month:02d}{d.day:02d}.nc4""

# list of urls for the files
fnames = [url(dti) for dti in dts]

# lets try to load the first 5 files
ds = xr.open_mfdataset(fnames[:5], parallel=True)
```

The error:

```python
