The logs are attached.

The image download timeout error is irrelevant as it is not the first error in the stack and is a subsequent error to the inital error.

The initial error is:

This is a General Error thrown by the camera; basically the camera is failing to take a picture even though it is receiving the correct command to take a picture.

The bad news is that in almost all instance I've seen this the camera is in it's final stage.  My only recommendation is perhaps to do factory reset and see if this resolves the issue.

I also found the solution and posting for other people who might come across this problem. I was attaching the EOS 70-200mm USM II lens with Auto Focus and Image Stabilizer turned ON. I had to set AutoFocus(AF) to Manual Focus (MF) and turn off the image stabilizer servo. After this I was able to get BYEOS to start clicking BIAS frames.

 

Since I have used this camera before with BYEOS, I was wondering what is different this time and I realized I used it with my C11 scope with a T2 adapter and did not see this. This time I am using this with a sky.

 

Another observation during dark frame subs for 90s/180s, The canon dial must be M and then clicking the Av+/- button to set the timer to BULB , otherwise BYEOS returns without doing anything

Fingers crossed that this was the issue.  Glad you got it to work.

There is no reason why the camera must be connected to either a telescope or a lens to shoot bias frames.

That was mistake and the plan was to build the Bias,Dark and Flat library.
