I've been using DK3WN's Online Telemetry Forwarder for the past year to upload 9600 baud Cubesat telemetry to the SatNogs database. Two days ago, after a PC restart, it stopped receiving KISS data from UZ7HO's High-Speed Sound Modem.

I've checked that the KISS ports are correct and there are no other demodulators running. The HS sound modem displays the telemetry data, but nothing shows up on the Online Telemetry Forwarder even though it shows the port is connected. I'm running both programs as Administrator.

OS is Win10. The Online Telemetry Forwarder is ver 1.0.14b HS sound modem is ver 0.19b. I'm using KISS port 8100 between the telemetry forwarder and the sound modem. HS Sound Modem has "KISS Optimization" checked and is displaying the received data, so it's working.

Any troubleshooting suggestions appreciated!
