I have not had the time to rebuild the flash as of yet but will soon. Honestly, I am a little afraid that If things don't work well and I loose my apps settings. I am not worried about re-configuring the ARRAY and POOL drives.
Meanwhile, I installed v6.11.5 and did the following and found out something interesting that may give you a clue as to how to resolve this problem:
1) All the auto-start apps started properly. I was able to get the GUI for 6 of them (Plex, Wireguard, Jellyfin, Nginx, Jellyseerr and Speedtest). The GUI would not start for 7 apps (Radarr, Sonarr, Nzbget, Unmanic, Krusader, Ombi and Handbrake)
2) I deleted Handbrake (I hardly use it) and removed the container completely and then reinstalled it. All went well and the GUI started.
3) I tried to start Krusader but as mentioned above, the GUI screen is unable to connect. Normally the url is something like this
http://10.0.0.74:6080/vnc.html?resize=remote&host=10.0.0.74&port=6080&autoconnect=1. I changed it to 10.0.0.74:6080 and got the screen below.
I restarted Krusader GUI again and I got the message that it is the first time I am starting Krusader and started the configuration. However, at one stage I got the following message
"Krusader's configuration file is in READ ONLY mode (why is that!?) Changed values will not be saved".
I hope that the above message will help you figure the cause of the problem.
