Download orbit file, failed

Hello,
I’m trying to do Apply Orbit Fle using snappy-python,
Previously, this always works without any error, but today I got this error:

WARNING: org.esa.s1tbx.io.orbits.sentinel1.StepAuxdataScraper: Unable to connect to http://step.esa.int/auxdata/orbits/Sentinel-1/RESORB/S1A/2018/01/: Read timed out

What’s the problem for this?
Thank You

Connecting with the browser to the URL works. The download of the files, too.
Maybe the server had intermediate problems?
Can you check with your browser and also with SNAP Desktop.

Ok,
Now its up and running again.

When I created the thread, i can open the link with browser and download the files,
Not quite sure on SNAP Desktop,
I thought there was some change on the link

Thank You
