Dear all,

I am encountering an error while running the following command:
getanc A2016031165000.L1A_LAC.x.hdf

The command appears to fail during a connection to the oceandata.sci.gsfc.nasa.gov API. Below is the complete error traceback for your reference:
Traceback (most recent call last):
File "/home/data/.local/lib/python3.6/site-packages/urllib3/connection.py", line 175, in _new_conn
(self._dns_host, self.port), self.timeout, **extra_kw
File "/home/data/.local/lib/python3.6/site-packages/urllib3/util/connection.py", line 95, in create_connection
raise err
File "/home/data/.local/lib/python3.6/site-packages/urllib3/util/connection.py", line 85, in create_connection
sock.connect(sa)
OSError: [Errno 101] Network is unreachable
...
(Full error traceback continues as attached or pasted above)

Based on the error, it seems the system is unable to establish a network connection to oceandata.sci.gsfc.nasa.gov due to the Network is unreachable error. The issue persists even after multiple retries.

This issue is new, as the command was working correctly in the past. I haven’t made any significant changes to the system or the network settings on my end.

Could you please investigate the issue? Let me know if additional details or logs are needed to help resolve this.

Thank you for your assistance.

There is no issue with the command. I just successfully ran As you noticed, it's a network problem. It could be on your side, on our side or in between. Please try agian.

Unfortunately I agree, it seems like a network problem. I just checked our servers' logs, and there has only been one request related to the string "A2016031165000.L1A_LAC", and the username attached to that request was "xuanyang02". So it appears that some network issue prevented your request from reaching us, from what I can tell

It might help troubleshooting if you tried to reach the endpoint that getanc is struggling with--does the link https://oceandata.sci.gsfc.nasa.gov/getfile/A2016031165000.L1A_LAC.bz2 work for you? It should download the file "A2016031165000.L1A_LAC.bz2"

Thank you for your immediate reply. Unfortunately, I still face the same problem
