What's Wrong?

I came back to my PC today and ran "claude -c" to continue yesterdays session but was greeted with:
API Error: 401 <html>
<head><title>502 Bad Gateway</title></head>
<body>
<center><h1>502 Bad Gateway</h1></center>
<hr><center>cloudflare</center>
</body>
</html>
· Please run /login

I ran /login and followed all the steps in the browser (authorizing, copying the key). The whole OAuth flow was super slugish and unresponsive though, but eventually got through. When I pasted my key back into the terminal, it again took a while for something to happen but I got this:
OAuth error: timeout of 15000ms exceeded

I tried multiple times, but it keeps happening. I can still open claude and it shows me as logged in, but when I try to send a message I get this:
API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"Invalid authentication credentials"},"request_id":"req_011CYwTbuZNPX8ALRy1YyGHN"} · Please run /login

I am using Claude Code v2.1.72 on WSL2:
WSL version: 2.6.1.0
Kernel version: 6.6.87.2-1
WSLg version: 1.0.66
MSRDC version: 1.2.6353
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26100.1-240331-1435.ge-release
Windows version: 10.0.26200.7840

I tested outside of WSL too, same issue. I don't think its a CC bug, but something wrong with the platforn. Raising this bug just for awareness. status.claude.com shows no issues.

What Should Happen?

I should be able to log into my account without OAuth timeouts.
