Looking for help with authorizing the eTrade API with oauth1

https://forum.golangbridge.org/t/etrade-api-authentication-could-not-be-completed-at-this-time/28660

I am still trying to resolve this issue. The tech support at eTrade just tells me to read the instructions. As far as I can tell, I am doing that.

I would appreciate any help or direction you can provide.
