Difference in CRS when reading with read_stars und read_ncdf

Question

I have a NetCDF file that I would like to load into a stars object. The two functions st::read_stars and st::read_ncdf both load it in, but the data ends up in different locations when I plot it using mapview. I think I'm not getting something really basic here and just wanted to ask what the best way is to read NetCDF-files into a stars object. (The one with read_stars ends up in the right location). I'm using the exactly same path.

The description of two objects look like this:

Read with read_stars

stars object with 3 dimensions and 1 attribute
attribute(s):
 DAILYPCP_198001.nc [mm]
 Min.   :0.00           
 1st Qu.:0.00           
 Median :0.00           
 Mean   :0.07           
 3rd Qu.:0.00           
 Max.   :4.10           
 NA's   :194505         
dimension(s):
     from  to                                           offset                                       delta  refsys point values
x       1 641                                           605720                                         250 unnamed    NA   NULL
y       1 643                                          5220237                                        -250 unnamed    NA   NULL

And the one read with read_ncdf

stars object with 3 dimensions and 1 attribute
attribute(s):

 3rd Qu.:0.00      
 Max.   :4.10      
 NA's   :194505    
dimension(s):
     from  to         offset  delta                       refsys point values
