Pack Download reaches 100% but says it failed

[TheScarletNape]

FAIR WARNING: This is my first attempt at building a modpack. I would not blame you if you ran far away from this thread! Having said that any guidance is appreciated.

 

I have built a basic modpack that I have loaded to my hosted web server. I can download the zip file directly from my browser and can decompress the file proving it is intact.

 

The launcher progresses through the download to 100% but nothing happens after that.

 

A file is created in the technic/modpacks/tp-sandbox/cache folder that is corrupted. 

 

The console log is not much help.

I have tried dropbox to eliminate my web server but have not been able to get it to work at all even with the work around mentioned in several threads.

 

Any suggestions on where to start?

Update: Was able to get Dropbox to work so it is something with the web server hosting the file. Not sure why Launcher has an issue when chrome and safari can download from the same url without issue.
