All,

While testing a python script, I noticed that retrieving data from the TIC catalog results in an error message, like this:

ticinfo = Catalogs.query_criteria(catalog="Tic", ID=tic).as_array()

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='mast.stsci.edu', port=443): Max retries exceeded with url: /portal/Mashup/Mashup.asmx/columnsconfig (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f670582d2e0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution'))

This mistake is temporary and did not happen last week. Is it caused by the MAST server being overloaded by too many requests ?

  • I tried the following and was able to get results. So maybe it was because MAST was being overloaded? `from astroquery.mast import Catalogs; print(Catalogs.query_criteria(catalog="Tic", ID=336732616).as_array())` – Avi Vajpeyi Oct 17 '21 at 00:38
