How to install Inouse applications via the web after the release of iOS 7.1?

Question

iOS

Having an Apple Developer Enterprise account before the release of iOS 7.1, it was easy to install company applications through the site using a link like:
itms-services://?action=download-manifest&url= yourdomain.com/manifest.plist
But after updating iOS to version 7.1 this method no longer works, the iPad or iPhone says that the site certificate is not valid (Cannot install applications the certificate for site is not valid - English version).
Googling the web revealed that Apple now requires HTTPS for this task .
Trying to use SSL with a self-signed certificate fails, iPad or iPhone says it can't connect to the site.
Alternatively, you can use the servicehttp://www.diawi.com , people have also tried using DropBox. But, to be honest, I want to use my own platform for distributing iOS applications.
Who has already solved this problem? How to properly configure and use HTTPS?

Answer 1

Get a normal (not self-signed) certificate and use it like before
https://startssl.com - free SSL certificate
or namecheap.com (about $10 for PositiveSSL certificate)

Answer 2

Free startssl is worse than the paid one, has limitations incompatible with normal operation. Paid certificate - additional costs. Renewing the certificate every year is also not an option. Self-signed can be done for at least 20 years.
In addition, the exact reason for the non-connection is not known ...
