NOT Resolved. Java Edition – custom skins not showing (only Steve/Alex)

Hello,

I bought a licensed Minecraft: Java Edition a few weeks ago, uploaded my skin — everything worked. Yesterday I accidentally launched an old pirate launcher, then reinstalled the game. Since then, the client always shows only default skins: for me it’s Alex/Steve, and on servers everyone is default too.

My skin is set in the profile, the profile page shows it, and the textures URL returns a valid PNG. No auth errors appear in the logs.

Account / profile:

• Microsoft/Xbox account: NineSword1472

• Minecraft profile name: SkulkNinja

• UUID: a44d8e85ac3a48b3b8920eba094419b9

Environment:

• OS: Windows 7 x64

• Java: Eclipse Adoptium 17.0.1

• Launchers: Official launcher and MultiMC 0.7.0-4235

• Game versions: 1.20.4 (vanilla and with Fabric Loader 0.17.2)

• Domain resolution looks normal:

– sessionserver.mojang.com → 13.107.246.77
– textures.minecraft.net → 13.107.246.77
– api.minecraftservices.com → 13.107.246.77

What happens:

• In singleplayer and on servers my character is default (Alex/Steve).

• On servers, all other players also appear as default.

• On the website the profile shows my uploaded skin; the direct texture link opens fine.

What I already tried (no effect):

• Sign out/in in the launcher, remove and re-add the Microsoft account.

• Full reinstall: delete .minecraft, caches and assets, clean instances in MultiMC, reinstall the official launcher.

• Run fully vanilla (no mods, no Fabric).

• Checked hosts (no entries for these domains), flushed DNS, tried different DNS.

• Disabled any proxies/traffic interceptors; launched without proxy parameters.

• Rebooted PC; tested across different launchers.

I can provide:

• latest.log with successful connections to sessionserver and minecraftservices and no auth errors.

• launcher_accounts.json (tokens redacted).

• In-game screenshots (I appear as Alex/Steve) and a profile screenshot showing my skin.

• The PNG skin file itself.

Expected behavior: the client should display my custom skin and other players’ skins.
Actual behavior: only default skins are displayed.

This looks like a cache/flag issue on the profile or the record the client pulls textures from. Please check my profile/skin on your side and advise what should be reset or how to fix so the client picks up custom skins again.

Thanks.
