Can't orbit files after March 2021

I was trying to finish the slaves splitting with python2 project.conf. But got told can’t find orbit files.

I went to the Copernicus Sentinels POD Data Hub website to download the files manually. I can’t even register a guest username.

Sentinel-1 orbit auxiliary files will be available at until 28 March 2021. Is it right? What’s the solution would be if we want to process the data after March 2021.

This is discussed here: Orbit file timeout (March 2021)
Please update SNAP to the lastest version 8.0.4 (including the removal of user configuration data).
