Re: [milo-dev] Error decoding symmetric message

[Daniele Menozzi <menoz.zone+eclipse@xxxxxxxxx>]

Yes, it's exactly the same. So my only chance now is to get in touch with the codesys support... I'm using the latest softplc code, I hope it's something that can be fixed with a downgrade...

Thank you very much, Kevin, your help is really appreciated!

Daniel,

I have seen this before and unfortunately it's a bug in the Codesys OPC UA server. If you can capture this happening on Wireshark we can verify it's the same thing I've seen previously, but I'm betting it's exactly like what is happening here: https://forum.inductiveautomation.com/t/opc-ua-failure-decoder/40371/10

Hi all,

I'm using Milo to connect a java application running on a linux server to a Codesys control PLC on a windows server, milo version 0.4.3 .

I recently started to receive the error " Error decoding symmetric message", you can see the full log attached here (and maybe you can see the log better here: https://codeshare.io/5oJgNp).

Do you know what can cause this issue? What can I check to fix this? Ideas?

Thank you very much

Daniel
