I have removed all password files, certificates and provision files to start from scratch.
1) Have generated in B4i a private sign key to create a certificate request file "certSigningRequest.csr". OK
2) Tried to request from Apple website by using Fire Fox browser a certificate. Got an error
==========
Invalid CSR
Select a valid Certificate Signing Request.
============
3) Repeated step 2 with Safari for Windows. Got an error:
===========
File Error
Your browser does not support FileReader API.
===========
Must say, that certificate request files generated in OS X (El Capitan) work fine with any browser, including the above ones.
Also I tried to get a certificate in OS X Safari browser by using a request file generated by B4i in Windows but got the same "Invalid CSR" error.
============
I have created CSR file with SSL command lines as you recommended in
https://www.b4x.com/android/forum/threads/invalid-csr.64288/#post-407155
and now browser accepted the file but finished with this
===========
AJAX ERROR
421
