SAProuter: Actual server name differs from requested one

I'm trying to connect to a partner's SAProuter.

I have received and imported the certificate as per screenshot.

My saprouttab file looks like:

KT "p:CN=Saproutersrv" * *
KP "p:CN=Saproutersrv" * *
P * * *

But I receive the error:

*** ERROR => SncPEstablishContext() failed for target='p:CN=Saproutersrv' [D:/depot/b 3638]
*** ERROR => SncPEstablishContext()==SNCERR_GSSAPI  [D:/depot/bas/74 3604]
      GSS-API(maj): Miscellaneous failure
      GSS-API(min): A2200202:Actual server name differs from requested one.
    Unable to establish the security context
    target="p:CN=Saproutersrv"
<<- SncProcessInput()==SNCERR_GSSAPI
*** ERROR => NiSncIProcIn: SncProcessInput failed (sncrc=-4;000000C251D4DF40;1449) [nisnc.c      1003]

What is wrong? Seems like the name of the certificate that I have might be incorrect or something. Is my saprouttab file correct?
