QuickBooks Error H202: Causes and Steps to Resolve the Server Connection Issue"

The QuickBooks Error H202 occurs when there is an issue while trying to connect to the QuickBooks server. This error prevents users from accessing key features that require an online connection like banking, payroll, billing and inventory.

Some common reasons why QuickBooks Error H202 may appear include:

Internet connection issues: If your internet connection is slow, unstable or offline, it can cause the error when QuickBooks tries to connect to its servers. Spotty WiFi signals are a major culprit.
Outdated application: Using an outdated or unpatched version of QuickBooks can result in compatibility issues with the backend servers. Make sure your QuickBooks is up to date.
Server maintenance: Intuit periodically takes its servers offline for maintenance, upgrades or repairs. Error H202 may appear during such scheduled downtimes.
Firewall/antivirus blocks: Over-zealous third party firewalls or antivirus programs can sometimes block the network traffic between QuickBooks and the servers, resulting in the error.
Too much network traffic: If several devices in your network are downloading or uploading large files simultaneously, it can slow down your connection preventing a smooth communication with QuickBooks servers.
Proxy server issues: If you connect to the internet via a proxy server at work or college, incorrect proxy settings in QuickBooks can cause Error H202.
