Hello Arno, Yes it is looking like I'll need to walk the user through using a packet sniffer. The external devices are all the exact same with some variations in the firmware. However, all the responses I've collected so far from different users show in their response headers support for HTTP 1.0 but with support for the keep-alive flag and the associated time-out and max-requests line too. The problem is only happening to one user so far but there may be others.
I definitely mean HTTP Keep-Alive. I connect to the external server with a plain old TWSocket (not THttpClient) and craft the HTTP requests myself, but the external device is definitely acting as an HTTP server.
