2 years ago Can you provide an indigo trace log of the problem. It may be camera driver related. I have checked the alpaca code and tested the camera simulator against ASCOM conformance checker and it reported no issues.

Last night I made some tests with the ALPACA Agent and I found that the property ImageReady never becomes true, causing download problems.
Standing to the ASCOM standard, the property ImageReady https://ascom-standards.org/Help/Developer/html/P_ASCOM_DeviceInterface_ICameraV3_ImageReady.htm should became true when an image is ready to be downloaded. If this flag is false, the property ImageArray https://ascom-standards.org/Help/Developer/html/P_ASCOM_DeviceInterface_ICameraV3_ImageArray.htm will fail with an InvalidOperationException.
I tested two ASCOM software (MaxIm DL 6 and Astroart 8) and both of these failed in downloading the image. Here the behaviour I found by looking at the trace log of the ASCOM ALPACA driver.

MaxIm DL looks at both CameraState https://ascom-standards.org/Help/Developer/html/P_ASCOM_DeviceInterface_ICameraV3_CameraState.htm and ImageReady. When the exposure start, CameraState changes from 0 to 2 and then, at the end, it returns to 0. MaxIm, watching this "toggling", starts the download using ImageArray. However, the property ImageReady is always false and this trigger the InvalidOperationException.
Astroart instead watch only at ImageReady, freezing in an infinite wait (since ImageReady never becomes true).

So please send us the full indigo trace log! it might be something driver specific....

and maybe connect your rpi to a faster network. try LAN cable?
