Hi ndubey2 , reviewed the thread and i'm not clear on a couple things:
- is there any http traffic on that virtual server, or is it all for this service?
- is the proficy client using mqtt or a proprietary protocol?
If you have a pcap of a sample transaction from client directly to server you can DM me, I'd be happy to take a look. Make sure to sanitize any credentials or IP. If mqtt, we can probably make this work pretty easily, though it'll be a learning process for both of us because i haven't done much with it yet. If not, what Paulius said is likely and you'll need to do a binary decode of the messages in the TCP data.
