With the help of a friend I realized the webui shortcut doesn't work properly. Yes, when using https://serverip:8181, it works. I'll look into changing the webURL. Thanks.
I'm also getting the "unauthorized" error and unable to load the GUI. It had been working fine for months so I'm confused since I didn't change anything. I've rolled the version back to 4.3.9-2-01 but the problem still exists. Does anyone have an idea why or what I can check? Thanks.
