Error in Polymer

I am trying to correct an EnMAP image through EnPT, with Polymer.
However, I get an error concerning the Copernicus web, as if the web doesn’t exist.
When searching for the web page, it seems to be under maintenance, do you know if there is another option to extract the climate data?

Please explain what this has got to do with Gitlab? Sounds like you are on the wrong forum as this is not a Gitlab problem.
