I still can't use VirtualBox since I purchased my unit. On 4.X it would just crash as soon as I started a VM instance, sometimes forcing me to hard reset the unit. On 5.X, now I just get a 404 Not Found nginx/1.18.0 error. Please fix your apps. This is also now a problem with Emby. It worked fine, then after a few weeks I would get a strange error in the frame that loaded on 4.X. Now I get a 502 Bad Gateway
nginx/1.18.0 error.

In TOS 4.2.30, you need to install the latest version of Vbox to use.
Whether you are using TOS 5.0 or TOS 4.2.x now? Because the installation paths of the two versions of the application are different, when you downgrade from TOS 5.0 to TOS 4.2.x, the use of the application may be affected.. You can try to reinstall the app.
