DietPi v8.1.2
I installed the Dietpi Dashboard (stable) and it seems everything works fine except for the terminal. I am able to connect to my node but after a while, the terminal becomes unresponsive and freezes. It happens every time.
there was an issue with freezing terminal sessions https://github.com/ravenclaw900/DietPi-Dashboard/issues/70
This has been solved 2 days ago. Try to install latest nightly. If you are still facing issues, try to connect to the GitHub issue linked above.
