I am trying to setup on premise builder with github enterprise integration.

Everything seems to work until I attempt to sign in.  
After signing in to github enterprise I am redirected back to my builder instance and then I see a call in DevTools Network tab to`/v1/authenticate/<state>` and a response of `{"code":7,"msg":"406 Not Acceptable- "}` and an http status of 401

Would it be possible to share the OAUTH\_\* env vars you used to configure your on prem builder instance? Redacting any secrets of course 🙂

IIRC, the Github Enterprise API has a slightly different prefix than public GitHub, but it’s been over a year since I’ve worked with an instance of it. The one item that would jump out at me is the OAUTH\_USERINFO\_URL, which _I think_ will a route prefix of `api/v3` (EX: `https://your-ghe-instance/api/v3/user` )

#!!)(@!&  
I missed the `/api/` before v3

fwiw  
export OAUTH\_USERINFO\_URL=https://\<your\_github\_enterprise\_host\>/api/v3/user  
export OAUTH\_AUTHORIZE\_URL=https://\<your\_github\_enterprise\_host\>/login/oauth/authorize  
export OAUTH\_TOKEN\_URL=https://\<your\_github\_enterprise\_host\>/login/oauth/access\_token  
export OAUTH\_REDIRECT\_URL=https://\<your\_builder\_host\>/

Thank you!
