Web AppBuilder Install Error 400

[BenGrod]

Could anyone provide some guidance with an error (400) I am getting when I attempt to install Web AppBuilder. I tried to install the Web AppBuilder about 1 month ago with only Esri's instructions and didn't get very far at all. With the help of Rebecca's blog and suggested links I have gotten pretty close but not quite. My error (400) is an invalid Redirect URI which are steps 3h and 3i in her blog. I ran through these steps a couple times changing the Redirect URI to include/exclude my company domain but its still not accepting them. Any suggestions would be welcome. Thanks in advance.

This is the way I am writting the ReDirect URI

https://mycomputername.companydomain:3345

http://mycomputername.companydomain:3345

FYI I also posted this same question as a comment to Rebecca's blog.

Ben,

   Not sure why you choose 3345 but the port that I use for that step is 3344.

Thank you Robert (and Rebecca Strauch), a typo was keeping me from success, insert embarrassed emoticon.

Ben, when Registering your machine thru ArcGIS Online as I mention in steps 3h and 3i, do not include any port.  Just add   http://computernae.companydomain and the https version.

(I responded to your question on the blog page the same way)
