Polar Alignment is not working right - no refresh was created by maxthebuilder

Hello,
I am still new to this.
I tried Polar Alignment before while using just a DSLR. It was very slow but kind of working.
Now I added a guider scope with a CCD to my setup and it's much faster.

When I run the Polar Alignment routine - it does its things - rotates, takes pictures, solves - all works great.
But when it comes to the actual alignment, when one selects a bright star to bring it to the cross...
I hit the "refresh" (every 1 sec) button and it refreshes once and stalls saying "cannot capture while CCD is acquiring".
Sometimes, after a minute or two it starts working again but after several frames stalls again, eventually forever.
Is there something in the settings I miss? How to get around this?
Thanks!
Max

Just guessing but It sounds like you have a very slow connection to the camera. If you are using wifi and are too far you can get very slow response that will cause that.

Sorry.
Added the info.
Nikon DSLR and ASI120MC-S. AZ-GTi mount.

INDI server was running on RPI.
Mount wifi-connected to RPI
Cameras usb-connected to RPI.
No hub.
RPI wire-connected to home router.

KStars/Ekos on Windows 7 desktop (with answr). Tried both 2.9.8 and 3.0.0.
Tried KStars/Ekos (3.0.0) directly on RPI.
Same result.

ASI Live View works (10-11 FPS)
I was using it unbinned (in Align module) since plate-solving was failing often with 2x2 binning

Thanks!

I was not far and it was a wired connection.
CCD's Live View works fine with 10-11 FPS rate.
Thanks!

Hi Jasem,
Tried two more times with the same result.
Yesterday - two cameras and AZ-GTi mount. Nikon DSLR and ASI120MC-S. ASI was used for mount alignments.
Today - just the ASI and AZ-GTi mount.
Attaching the log (polar alignments start at 22:29:45) and a screenshot.

Symptoms:
-- start polar alignment
-- three rotations go as supposed to
-- in the end, when I hit "Refresh" I get one image (sometimes two) and then the procedure stalls saying "cannot capture while CCD is acquiring".

Thanks for looking into this!
