Can't upload pictures

[Sganus]

When I try to upload an image it gives me an error "Upload failed. The server returned an error!" while the import from a link works normally

Can you check the logs?
Can you provide us with a copy of your diagnostics?

I've found the fix. It was because lychee is behin my swag reverse proxy and in TRUSTED_PROXIES= it was null
I change it by * and now I can upload my pictures from my hard drive
