Hello Andrea, I think the problem is somewhere else. I found this issue on Atlassian a few days ago: https://osgeo-org.atlassian.net/browse/GEOS-10951?search_id=3078624a-bb7c-4187-a594-9a5720088e37 I'm using the latest available dockerized version of MinIO. Maybe something is wrong with just the object storage setup. Or maybe I'm putting the wrong URL in Store GUI. Something like cog://http://172.17.0.2:9000/dev/cog.tiff should work with MinIO available at 172.17.0.2:9000, bucket dev and object cog.tiff, should't it ? Shall I also set up a region for my MinIO docker instance ?
Have a nice day, Marek po 24. 4. 2023 o 19:00 Andrea Aime <andrea.a...@geosolutionsgroup.com> napísal(a): > Hi Marek, > the system property is currently the only way to go. > > Best regards > Andrea > > On Sun, Apr 16, 2023 at 8:00 PM Marek Kadlečík <marekkadleci...@gmail.com> > wrote: > >> Hello folks, >> By investigating the stuff, I assume the error is caused by http range >> request rejection from the side of MinIO.
