The quickbook stops the database server every so often, I can not find any reason. I have the quickbook premier 2019. I also find a message and I have everything well configured in the firewall, attached image.
It seems like the firewall is blocking QuickBooks from running, jarour.
You'll have to configure your firewall manually to get this fixed. Please follow the step-by-step instruction in this article under "Configure firewalls manually":
Configure firewall security settings for Desktop.
Let me know if you need further help. I'll be sure to get back to you.
