Downloading error through ad hoc

Hello, I faced with very hard problem, which I tried to solve for day but in vain. So, I have individual developer account. On my personal page I added 2 more devices except my. This devices belong to my coworkers. Also, I added this devices to my iOS Development provisioning profile. Next, I tried to deploy my app (after archiving it) through ad hoc. All devices were added to ad hoc provisioning profile too.

Then, I saved manifest.plist file and app_name.ipa file.

I downloaded .ipa file to internet and made it's own download link. I opened manifest.plist and substitute first link (which I indicated in Xcode during making manifest and .ipa files) on created in internet download link for .ipa file. After this changing I downloaded manifest.plist file in internet and made it's own download link. I copied this link and concatenate it with itms-services://?action=download-manifest&url=

after that I send this link to my coworkers and they tried to download app, but during loading error occurred. How to solve it? Thank you!
