PyAPS authorized and acepted the terms but failed to download

Hi everyone,

I used to successfully download grib files of ERA5 using PyAPS during MintPy processing, but recently I have a problem when downloading the grib files of my new study area. Here is the error:

I tried to solve it and then I updated the PyAPS to latest version. I tested pyaps3 by run  the scripts TestPyAPS.py (located in ./PyAPS/examples/), but unlukily another error came like this:

(mintpy) [zzusaa02@login05 ~]$ python testPyAPS.py

Even if I re-created a new account of CDS, these two errors still exsist. Could you please give me a hand?

Best

I think they have been experiencing some issues. I had the first error you report earlier in the week.

I hope this helps.

Thanks for your reply, sir. I can download ERA-5 files through the API python code on my terminal but failed in MintPy. I later  manually  downloaded the ERA-5 files from the website and successfully ran the step of tropospheric correction.
