I think that remote connection is not working - SAP in other ticket said, that they have problem with connection.
When I run Sap Service Connector with one of this small files, in logs I can see this kind of entries:
Wed Jun 25 01:46:33 2014 CONNECT FROM C32/- host [my-home-ip]/17434 ([my-home-hostname])
Wed Jun 25 01:46:33 2014 CONNECT TO S32/24 host 194.39.131.34/3299 (194.39.131.34) (p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE)
Wed Jun 25 01:46:33 2014 ESTABLISHED S32/24 (-/SNC)
Wed Jun 25 01:46:34 2014 DISCONNECT C32/24 host [my-home-ip]/17434 ([my-home-hostname]) RST
How can I check if the certificate is still valid?
