Kde connect failed to reconnect with android after a while on Windows

After pairing my android with window, all functions work well without any issue.
While after a few minutes, device become disconnected. Both devices can still see each other in the search list, if I unpair and pair it again, it will become disconnected immediately after clicking accept.
After tracing the packets, it seems the server on windows refuse the tls connections.


10.3.0.1 is the windows app
10.3.0.2 is the android app

But when I logout Windows accout and login again, it can connect normally and become discconect after a while.
I’ve tried resetting the Windows app (deleting the key and certificate and all configs) and the Android app on both sides, but it didn’t work at all. Only logging out and back in seems to restore the connection.
Any ideas?
