Hi there, @abartonek.
I'm here to help you get past the Error H202 that you received so you and other users will be able to utilize QuickBooks smoothly.
The Error H202 means that something is blocking the multi-user connection to your server. The steps below got you covered on how to resolve this issue.
You'll need to do the following:
