Why i can´t turn a Stoutnail into a Fleshrender even when i’m in ladder/solo?
The recipe upgrades the unique base, not its identity.

Sarevok is correct.
The same also applies to the new set upgrade cube recipes. Here’s a snip from The Arreat Summit on unique item upgrade recipes:
1 Ral Rune + 1 Sol Rune + 1 Perfect Emerald + Normal Unique Weapon = Exceptional Version of Weapon
This formula changes the base item type from the normal to exceptional version. For example an Axe is turned into a Cleaver. This does NOT convert the item to the Exceptional Unique version of the Unique Item. Unique item bonuses remain the same; only the item it’s based on is upgraded. This can be used to upgrade Ethereal Items also. They will continue to be Ethereal after they are upgraded. Also if the item is socketed, then jewels or runes and their mods will also remain.
1 Tal Rune + 1 Shael Rune + 1 Perfect Diamond + Normal Unique Armor = Exceptional Version of Armor
This formula changes the base item type from the normal to exceptional version. For example Quilted Armor is turned into Ghost Armor. This does NOT convert the item to the Exceptional Unique version of the Unique Item. So you cannot for example use this formula to transform Greyform into The Spirit Shroud. Unique item bonuses remain the same; only the item it’s based on is upgraded. This can be used to upgrade Ethereal Items also. They will continue to be Ethereal after they are upgraded. Also if the item is socketed, then jewels or runes and their mods will also remain. Armor refers to any sort of armor, including helms, boots, belts, gloves and shields, not just body armor.
1 Lum Rune + 1 Pul Rune + 1 Perfect Emerald + Exceptional Unique Weapon = Elite Version of Weapon (Single Player, Ladder Only)
This formula changes the base item type from the exceptional to elite version. For example a Cleaver is turned into a Small Crescent. This does NOT convert the item to the Elite Unique version of the Exceptional Unique Item. Unique item bonuses remain the same; only the item it’s based on is upgraded. This can be used to upgrade Ethereal Items also. They will continue to be Ethereal after they are upgraded. Also if the item is socketed, then jewels or runes and their mods will also remain.
1 Ko Rune + 1 Lem Rune + 1 Perfect Diamond + Exceptional Unique Armor = Elite Version of Armor (Single Player, Ladder Only)
This formula changes the base item type from the exceptional to elite version. For example Ghost Armor is turned into a Dusk Shroud. This does NOT convert the item to the Elite Unique version of the Unique Item. Unique item bonuses remain the same; only the item it’s based on is upgraded. This can be used to upgrade Ethereal Items also. They will continue to be Ethereal after they are upgraded. Also if the item is socketed, then jewels or runes and their mods will also remain. Armor refers to any sort of armor, including helms, boots, belts, gloves and shields, not just body armor.
So how can i upgrade its identity? or just droping the fleshrender already upgraded? I could swear that i could upgrade one into another in D2 classic ladder/solo 
…

Sounds like maybe when you got bored or d2 maybe downloaded a mod to play on for a while.Sounds like something they would put in a mod
You can’t. Need the unique you want to drop, otherwise, things like Harlequin Crest, Ormus’ Robes, Windforce, etc would be pretty easy to obtain…
I think you’re right.
