connection to oceancolor.gsfs.nasa.gov timed out

[zhangke123333]

Hi
I can't access the oceancolor website on Linux using Firefox ,why?
Is there a change in the website license and what should I do?

Looking forward to your reply! thanks!

No change. Try clearing your browser cache, closing and restarting the browser. Please let us know if you are still experiencing the issue after testing.

Hi
Thanks for your reply. but...
Sorry say that it does not work even after clearing the browser cache. The tip is: Connection timeout.This caused my python script to not run, which is used for generating Level2 data from Level1 data.
I can browse any other site except ocean color and I'm sure my internet is fine.what should I do next?

Looking forward to your reply! thanks!

What action you are taking that results in the timeout message?

I just access the oceancolor website on Linux using Firefox. The tip is: Connection timeout.

And, the OCSSW (seadas 7.5.3) can not generate GEO file form L1A_LAC.

execution exception: java.io.IOException: modis_GEO.py failed with exit code 1.

Do you have a .netrc file in your home directory that has your Earthdata Login credentials?

https://oceancolor.gsfc.nasa.gov/data/download_methods/?tab=download-methods-tab#netrc

Also, if you are running SeaDAS on linux, please update your SeaDAS to 8.3.0. We no longer support 7.5.3. https://seadas.gsfc.nasa.gov/

Occasionally, timeouts happen in network traffic, see viewtopic.php?t=3729
