Hi Philip, I tried to send as2 messages to mendleson test server using the class MainSendToMendelsonTestServer but with no success. Getting : connection reset 2021-02-09 13:29:17,398 ERROR [main] (AS2Client:444) - Error sending AS2 message com.helger.as2lib.processor.AS2ProcessorException: Processor 'DefaultMessageProcessor' threw

Do you know how to fix this issue? Thanks, Itay

That depends on your VPN setup. Check your VPN gateway for specific firewall rules. Sometimes access to the Internet is not allowed while you are in VPN. Best to contact your VPN operations guys. Maybe it's just an ackward port and only 443 would be allowed? No idea. Maybe the other side is rejecting your message, because your outgoing IP address changed or you are sending a different client certificate? So many options ;-)

Try telnetting to the other side and see if that works - if yes, than they are rejecting your message. If no, search on your side.

Hi @phax What host should I check? The server is http://testas2.mendelson-e-c.com:8080/as2/HttpReceiver what to check on telnet? I tried telnet testas2.mendelson-e-c.com with no sucess Thanks, Itay

Hi @phax I checked it is working via https://testas2.mendelson-e-c.com:8444/as2/HttpReceiver https is working with vpn http not Thanks, Itay

Okay, so it seems like your VPN is not allowing http connections to the outside. Good to know ;-)
