My metahuman live link face suddenly stopped working

The live link face works well at first, but it failed suddenly, I did nothing at all.

The source looks good in the live link hub, but I can’t select the subject from the list in my level for the metahuman.

I’ve restarted the editor and live link hub for many times and even the whole computer.

And I’ve try to add anoter metahuman actor in my level, and also not work well.

What’s the problem here?

The clients list is empty, it didn’t conneted to my Editor.

PS:I found the error int the live link hub’s log
