keeneticOS developers replied that "the client does not know how to handle LCP Configure-Nak"
can this problem be solved?

It's strange because it work with all Windows/Mikrotik implementations.
Maybe the debug log may help to understand the problem.
Anyway the log contains a lot of informations, so is better if you send it to android@colucci-web.it

Here the steps to get the log:

• edit the VPN

• tap on "Options"

• select "Set log level" and set the value to 3

• save the changes

• connect the VPN

• wait for the error

• disconnect the VPN

• export and send the log

After the test, remember to edit the VPN and unselect the "Set log option"

send it to android@colucci-web.it

I sent a log to email

Thank you very much for the bug report.
The problem was related to a bug in the LCP negotiation.
The problem has been fixed in the new release 1.00.22 that will be available shortly
