Range of blend too large

I’m learning how to 3d model in shapr and I’m trying to fillet the corners of this object. I could do it in some edges, but not on all of them. I have no idea what to do, could someone help?

Here’s my object
Thanks

Often simply changing the order you do the fillets in will make it work. If you’re filleting everything to the same radius, try selecting all edges and doing the fillets in one operation.

I’m sorry but I have tried to fillet the error area first. Simply cannot understand why. I’m wondering if the segment is too long to fillet, but i dont know to segment this line
