Hi Community,

I currently working on a NextJS Auth0 proof of concept. I’ve been having been making a lot of progress thus far, however, I have stated to get an error that I cannot find any reference to. I’m current using the @auth0/nextjs-auth0 npm package.

Login handler failed. CAUSE: Discovery requests failing for [https://llamapass-dev.us.auth0.com](https://llamapass-dev.us.auth0.com), outgoing request timed out after 5000ms

This started happening after a few days of testing my application and working through a couple of tutorials and testing.

Any ideas as to what is causing this error and how to resolve it?

I had exactly the same problem. After I went through the nextjs tutorial everything worked fine. And then I encountered the same error (I can not tell if I have something installed on my system).

On my machine (Fedora 37) it was an ipv6 problem. As a workaround I use the following line in `next.config.js`:

```auto
const dns = require("dns");
dns.setDefaultResultOrder("ipv4first");

```

[https://nodejs.org/api/dns.html#dnssetdefaultresultorderorder](https://nodejs.org/api/dns.html#dnssetdefaultresultorderorder)

This forces nodejs to favor ipv4 over ipv6.

Some more details:

`nslookup <mydomain>.us.auth0.com` returns the following

```auto
Address: 104.16.170.253
Address: 104.16.171.253
Address: 2606:4700::6810:aafd
Address: 2606:4700::6810:abfd

```

While a GET request to the discover URL (`https://<mydomain>/.well-known/openid-configuration`) over ipV4 worked (returned a 403 but that was expected). The same request over ipv6 encountered a timeout.

Maybe I will open an issue on github, but not exactly sure if this is the right place.

The dns workaround did not work for me. Has anyone else come up with a solution to this problem?

turns out my issue was a bad copy paste job of key values in my vercel env settings
