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.
