Hi Jan,  
Thank you so much.

Your answer help me solve the problem.

This happen because of mine. Plugins folder had not been set in persistent volume, so when I upgrade to new version image. It’s been gone That’s the problem.

I just copy all plugins to container and restart. It worked.

Thanks again.
