Mac App Store blocked by KIS [19 and 2020, "Cannot Connect to the App Store" ]

[PvT]

Edit: I spoke too soon. I am still getting the "Cannot Connect To The App Store" on the Home Screen which is the "Features" tab. The other tabs; Top Charts, Categories, Purchased and Updates seem to be populating fully with images etc. They did not at first, but after turning protection off, opening app store, closing app store, turning protection on and restarting the iMac, it seems to work properly with the exception of the first screen "Featured" which shows "Cannot Connect To The App Store" Though I am happy with the improvement with the lates KIS version 20.0.0.829a I had the same problem in not being able to access the App Store on my 2011 iMac running High Sierra. The problem began a few days back. After countless fix attempts, to no avail, with the help Uncle Google, I finally thought that maybe Kaspersky Internet Security is the culprit. When I disabled it, the App store finally worked. Then I found this discussion, upgraded to 20.0.0.829a and it now is working fine. Thanks to everyone on this thread!

Hello PvT, Thanks for posting:pray_tone3:. The reason I'm checking with SupR-Pingou, is bc, you advised the issue is fixed (for you) with (a)... I would like everyone who doesn't have (a) to: update, reboot, run a manual databse update, recheck and let me know please? Thank you.

Hello FLOOD , Yes my KIS version is up to the "a" version. From what I understood from PvT the issue is still present. From what I saw on my side images are probably showing up on certain tabs because they are in the mac cache system : I have the same thing on my side. When I try loading a page where you have an image showing up, next page is somehow loading but images etc don't on Apple music. Waiting for a fix from Kaspersky team (see my last post). Regards

Hello SupR-Pingou, Thank you for replying:pray_tone3:. Maybe I've completely misunderstood PvT - when he/she says "upgraded to 20.0.0.829a and it's now working fine".:thinking:

Hello FLOOD , His post was edited, perhaps you only have seen the original post without the edit. :)

Hello FLOOD and SupR-Pingou, I have not "yet" reported to Technical Support, will try and get a brief message out to them shortly. Thank you SupR-Pingou what you have pointed out seems to be absolutely correct that it was the cache that was still giving me images on many of the App store tabs. As when I started up my iMac this morning, almost everything populated in the App Store, surprisingly even the first "Features" tab had populated fully. see below Although, when I followed the following: https://macreports.com/mac-cannot-connect-to-app-store-fix/ I was back to an empty "Features" and "Top Charts" tab, "cannot connect to the app store". The following tabs populating, but with some missing images. You may be able to suggest a better cache clearing as I do not believe I am doing so completely. If I turn NIS Protection off, all Mac App Store tabs completely and fully populate with all images. Best regards, Peter

After upgrading my Mac to Catalina and get new apps TV & Music I discovered that KIS 20 protection make those 2 apps not working properly. TV app content not showing and Music iTunes Store is blank I try to uninstall & reinstall KIS 20 I try to reinstall Catalina upgrade Nothing fix the problem The only thing that can fix the problem is to stop KIS protection Once KIS protection turned off everything works fine Is there any fix to this issue

Hello ehabjadalla, Welcome! This is a know issue, please read Mac App Store blocked by KAV19, "Cannot Connect to the App Store", & please contact Kaspersky Technical Support. Note, the reference topic title says KAV19, however, as you read the 3 pages, you'll see it's pertinent to KIS20. Thank you:pray_tone3:

Hope this issue will be solved soon //Mode edit: Lots of us do; but this topic is temporarily and amicably closed until new and useful information becomes available to make a post postworthy enough to post. :)
