Certificate SSL on RouterOS - Errors / Problems

Hi,

I want import certificate on RouterOS; I have used this command:

/certificate template add name=server country=IT ca-crl-host=<ip address> common-name=<domain name> email=<email>

then I have used:

/certificate create-certificate-request 
template: server
key-passphrase: *********

and I have on store 2 files:

certificate-request_key.pem
certificate-request.pem

I have send to CA the content of certificate-request.pem and it send me the response, I have copied the content of certificate to file:

certificate-response.pem

When I try import on RouterOS i receive this error:

[admin@RouterOS] > /certificate import file-name=certificate-response.pem 
passphrase: *********
action timed out - try again, if error continues contact MikroTik support and send a supout file (13)

How can resolve this problem?

Thanks.

Resolved with 6.15, but after not working IPv6.

I am using RB1200 with RouterOS 6.19.

I cannot get /certificate template
says:
bad command name template (line 1 column 14)

is there something additional package required to make template working?
