I'm trying to respond by saying Thank You to the QB representative who provided a quality answer to my Community Post

Good day kogawa.

The "Authentication Ticket Mismatched, failed authentication" error in the QuickBooks Community forum typically indicates a problem with your login session . Let me guide you the troubleshooting steps.

Here’s how:
 

1. Log out of the forum and close your browser completely.
2. Try to open an Incognito/Private window and log in again.
3. If that still doesn't work, try a different browser.
4. Ensure your browser is up to date.

If these steps do not work, the problem may be temporary and related to the forum's authentication service.

For other issues and concern, our Community Team is always here to assist you.

Hi @kogawa,
 
I just wanted to follow up to check if the resolution we provided helped resolve your issue.
 
Please let us know if everything is now working as expected or if you're still experiencing any problems.

We'll be glad to assist further if needed.

Yes I believed that worked through Incognito mode, thank you.

Thank you for confirming, @kogawa.
