Hi, this sounds like the same issue as in this thread: [I can no longer log in to Simbrief Dispatch in MSFS 2020](https://forum.navigraph.com/t/i-can-no-longer-log-in-to-simbrief-dispatch-in-msfs-2020/18061)

Please follow the solutions in that thread (notably, updating to the latest version of the SimBrief plugin) to see if that helps.

Best regards,
