I have experienced "lost connection to backend" errors but those went away when I switched to wired ethernet (from wifi). Also, even on wired ethernet, I find that the connection will be lost if there is a lot of scp or ssh activity so I throttled this with a qos script. The slowness of ui navigation might also be due to mysql not being optimized. I noticed speed improvements in navigation when I started optimizing my mysql database.
