Describe the Bug
I have two machines running Sunshine. When I attempt to adjust my config via the webUI, I can only save the changes if I'm accessing the WebUI via the host I'm trying to change. I can access the UI from other PCs on the network, and Origin Web UI Allowed is set to LAN.
When I click save, nothing happens.
I've tried clearing cache, multiple browsers.
Expected Behavior
I expect to be able to modify the config via the webui from any machine on the LAN.

ReenigneArcherI have some additional info.
When accessing the webui directly from the host, I can only make changes from localhost:port
If I try hostname:port or ip:port I can load the webui, but changes won't save
You need to add your hostname to the https://github.com/LizardByte/Sunshine/blob/master/docs/configuration.md#csrf_allowed_origins setting.
