Dear,

I can’t post the following in our discourse instance, would you help me why it could be?

More information: I tried as admin, or as basic user.
I’m trying to post to a sub category.
When I try to post without the code it works, then I can edit the post and add the code.
However if I try to post at once, it gives the error “Oops! This page doesn’t exist or is private”


Hello
when I use the OpenSearchAPI I get a response with multiple products.
The services section for a product looks like this:

 "services": {
   "download": {
     "url": "https://catalogue.dataspace.copernicus.eu/download/6181e91f-df75-518d-89bf-b57c3ad1b4ea",
     "mimeType": "application/octet-stream",
     "size": 61062129
   }
 },

Unfortunately, the URL doesn’t work. When trying to download a product I get a 301 HTTP (permanently moved) error. The response does not provide the URL of the new location.
To download the product, I now use the OData URL:
https://download.dataspace.copernicus.eu/odata/v1/Products({ID})/$value

But actually, the provided URL should work, right?
