Why can I not post to the community forum. i keep getting " Authentication Failed "Authentication Ticket Mismatched, failed authentication.Return to my original page

I’ll help you post in the QuickBooks Community forum, LDO.

Let’s determine whether this is a web application issue. Start by logging out and logging back in. Then, refresh the page to ensure it updates properly. Once done, access the forum and attempt to post again.

If the same error occurs, clear your browser’s cache to remove outdated files and improve performance. Next, confirm that you’re using a supported and updated browser for optimal compatibility with QuickBooks.

Feel free to reach out if you encounter any other issues. I’m here to help.     

I tried deleting all history as well as all searches. Made all other tasks more difficult and still no lcuk signing into community
