Can i know whats wrong with this product name " باور بانك زندور 26800 mAh مع شحن سريع فضي" im not able to sync it .: Business Validation Error code - 6000

Let's perform some troubleshooting steps to get rid of the error message, faissal.

I've checked here on my end and there's no reported case about this one. The Business Validation Error -6000 occurs when QuickBooks Online (QBO) connections need to be validated by the system.

To rectify this one, let's try accessing QuickBooks Online (QBO) using a private or incognito window. Then, try syncing the product item again.

Here's how you can access private browser:

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge: Ctrl + Shift + P
• Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N

If it works, clear your browser's cache to delete those temporarily stored files on your browser's data. You can also use other supported, up-to-date browsers to be thorough. 

If the same thing happens, let's try clearing Intuit-specific cookies to refresh website preferences on your program. Just proceed to Step 2: Clear Intuit-specific cookies from your browser section in this article: Clear cache and cookies to fix issues when using QuickBooks Online.

I've got a link here where you can find articles about running your business in your account: https://quickbooks.intuit.com/learn-support/help-articles/misc/03/help-articles-global?label=QuickBooks%20Online.

I'm just one post away if you need anything else in QBO. I'll be around to provide additional assistance. Keep safe and healthy.
