Problem working with AirSane

[jmarchewka]

Hello! I am having an issue using this on an iPad (MYFY2LL/A, 16,4,1(a) ) and communicating with an AirSane instance (https://github.com/SimulPiscator/AirSane.) My AirSane instance does work on my Mac mini M2 with macOS Ventura 13.2.1.

When I launch OpenAirScan, it finds the scanner, but it just shows a spinner for the space where the icon would be, and when I click on the scanner, the next page has no options. Clicking 'Custom Scan' and then 'Start scan!' just brings up an red banner stating 'the scanner is busy!'

I have checked the URLs and they are using self-signed certificates, but I am able to access them with the iPad. Here is the output from Bonjour (via the Discovery app) for the scanner along with the XML from the ScannerCapabilities endpoint.

Thanks for any help you can provide!

I'll have to spin up an instance of AirSane myself to troubleshoot this.

The image doesn't load as there is no image specified in the path returned by AirSane, it's just a directory.

The image doesn't load as there is no image specified in the path returned by AirSane, it's just a directory.

That URL does point to a valid image. I am not sure if the escl spec requires a filename.
