Could it be possible !2443 does induce a non negligible delay when restarting/powering off a PinePhone ?
Since this morning I upgraded EG25-manager using apk and it's now taking about a minute or so to shutdown pmOS.
Phosh does stop and it's stuck at the shell login screen
I'll try to get more info later using serial cable...
