Multi radio setup with skydroid T10

Hii,
I’m new to pixhawk i wanted to set up multiple radio for 150 km flight of my vtol so as ardupilot guide suggested I connected other radio SBUS in telemetry 2 and configured serial port accordingly now my both radios are working when either of them is on. And for telemetry I made telemetry extender and connected two telemetry to them. I’m using skydroid t10 transmitter. I just took a test flight mission via mission planning drawing waypoints. Everything was connecting yesterday but today suddenly I can’t connect telemetry (i.e. radio Skydroid t10 is not connecting to mission planner) but the same radio is connecting telemetry on Jiyi k++ and connecting to agri assist app. Even I upgraded the transmitter.
Please guide me how do solve this problem and connected skydroid t10 to mission planner.
