Hello there, @EO2021.

I've seen that you've posted twice in this forum with the same concern. Don't worry, my colleague has already provided information about the Webconnector logfile from filling up with debug messages. Feel free to visit this link: https://quickbooks.intuit.com/learn-support/en-us/other-questions/re-technical-webconnector-logfile-...

To learn more about handling Web connector errors, check this article: Fix common Web Connector errors in QuickBooks Desktop. 

Please let me know if you have follow-up questions about Webconnector or anything else about QuickBooks. I'll be more than willing to answer them.
