Communication Error

[Nylluun]

I have been seeing many people get this error, but there is never a good discussion about how to go about it. Here is my log.

I am almost sure this is a problem with my api on IIS. I've customized the files in the api folder correct i believe, I just don't think I configured IIS correct. Here are some screenshots of MSSMS and IIS: Help - Imgur , My SQL Server Port is set to 50427. I've change the files to match it, but that is on my possible problem list as well.

Let us all collaborate and try to fix this matter
