Yeah, me too. Simlink authentication just hangs. No good.

Simlink hangs when authenticating user… Frustrating…


It was issued with access to the Simlink configuration.

To fix just follow these troubleshooting points.

  1. If you install the Simlink on macOS.
  2. if you install the Simlink on Windows.

Please let us know if the issue is fixed or not.

Worked!! Thank you. Quick one, why is Simlink separated / stand alone from charts?. Shouldn’t it be embedded into the Navigraph charts app/program, i/o separate installation. And giving the user the ability to disable moving maps within charts?. Thanks

It is currently separated for historical and cross platform reasons. In time it is planned to be fully integrated into Charts.

You can toggle Moving Maps in Charts :


Thank you Ian, yes I can toggle Moving Maps within charts, I meant more from an installation and integration standpoint. It would be lovely to have Simlink embedded into charts on a single installation i/o 2 different installations and programs running side by side. Glad to hear its in your roadmap as well as Vatsim integration. Cheers
