OAuth error: fetch failed

[egarl004]

When attempting to authenticate, "fetch failed" error is presented after authenticating via web browser. Sign in methods did not yield different results.

I was having the same issue but resolved when removing vpn connection. Worth a try if you're behind corporate vpn/firewall as well.

I did suspect this, disabled vpn and still had the same issue though on my end.

This is probably due to the ssl certificate chain being broken by zscaler/other SaaS solution used in company networks. Experiencing the same issue...

I am having this same issue with a vanilla internet connection, no vpn, macos, zshell, nvm, v16.14.0, tried both chrome and safari as default browsers. sometimes i get to a key that i can copy in the browser but the shell script will not accept it, shell and browser process seems not to be in phase, just dancing around.

I am expereincing the same issue above.

Wondering if this is something Claude Code can fix...

[FoRJu]

this is fixed with ChatGPT with terminal. Update node and npm to latest version. All fine.

npm --version
10.9.2
node --version
v23.9.0

os : Ubuntu 22.04 LTS
node -v : v20.18.0
npm -v : 10.8.2

In my case - with nvm - the issue was a lingering prefix in .npmrc pointing to an older version of node. Now clearing this, with node version
node -v
v20.11.0
it works fine.
