MessageHTTPUploader.performUpload: [ConnectException]: Connection refused: connect


I have installed AS2 build 49 and 51 and tested on both the versions.
I have exchanged the certificates between two local systems and I am getting the following error.

MessageHTTPUploader.performUpload: [ConnectException]: Connection refused: connect
mendelson_opensource_AS2-1496401946678-0@revlocal_promtest: Connection problem, failed to transmit data.

I don't see to miss any configuration details. Could you advise the solution ?

When I click the MDN url using a browser for https , I get the following error.

Turn on TLS 1.0, TLS 1.1 and TLS 1.2 in Advanced settings and try connecting to again. If this error persists, it is possible that this site uses an unsupported protocol. Please contact the site administrator.

It would be great if you could shed some light.




Just want to give some more information on this issue.

The whole AS2 set up was working fine and been tested with a partner A. And then another partner is configured and that's when the issue has started. So I have uninstalled build 49 and installed 51 and since then I am unable to have a successful SSL connection. Please advise.

Hi there ,

thanks for getting back to me quickly.
I am not using a java program. I am getting this error when I try to send a file to a partner using mendelson opensource AS2v1.1 GUI. Any advice ?


"I am not using a java program."

in which language do you think it's written the mendelson opensource AS2? Why are there so many .jar files? ;)
