Plate solve failed

Sequence Generator Plate Solving

Hello,
(this one may be for you @Andy !)

My plate solving using local ansrv use to work perfectly until yesterday ( I had to switch to remote astrometry.net for yesterday session)

I just tried a compact version of the faillure:
open SGP, load an image from last night, solve with remote astrometry.net (that works), then switch to local astrometry.net server, and it failed.

SGP log filed attached, but not very verbose, the only meaningfull line (I think) is:
[05/01/17 14:30:07.954][DEBUG] [Unknown] Exception in Astrometry.NET Solver: Object reference not set to an instance of an object.
sg_logfile_20170501142806.txt (37.4 KB)

I launched the ansrv watcher and got this:

Please let me know how to proceed?
(get more log from somewhere?)
Thanks!

Olivier,
There are a couple possibilities.This could potentially be related to your Antivirus software. Try temporarily disabling you AV … does that make the problem go away? (and does it come back when you turn it back on?)
If it is not AV-related, it could be related to a bug in cygwin that will require an update to the ansvr package. Are you running Windows 10?

Looks like perl (the process running ANSVR) failed. Have you attempted to restart ANSVR or restarting your machine?

Thanks,
Jared

Thanks Andy,
I confirm this is AV related, as it does work when I turn off my AV (Avast) and stop working when I turn it back on.
Do I need to an an “exclusion” to my AntiVirus ?
Thanks,
Olivier

I’m not sure how to do it in Avast, but the file to add to the exception list would be

C:\Users\Olivier\AppData\Local\cygwin_ansvr\bin\perl.exe
