Hi there, Thank you for reaching out, WEASEL is a general network error, so even though it only happens on Steam, it usually means something about the connection between your PC and Destiny’s servers is unstable right as the game is trying to log you in. A few things to try: Verify your game files on Steam Right‑click Destiny 2 in your Library → Properties → Installed Files → Verify integrity of game files. Power‑cycle your network and PC Fully shut down your PC. Unplug your modem/router for ~30 seconds, then plug them back in and wait until they’re fully online. Start your PC and launch Steam → Destiny 2 again. Use a wired connection and close VPNs/overlays If you’re on Wi‑Fi, try testing with a wired Ethernet connection. Temporarily disable VPNs, network “optimizers,” and overlays (Discord, Steam overlay, capture tools) while you test.
