Application doesn't start on Windows and IIS returns 502.3

Fix a Windows-only startup issue in versions v5.38.0 to v6.11.0.

Problem

On Windows in some environments, WProofreader Application Server may fail to start in versions from v5.38.0 to v6.11.0.

Fixed in v6.11.1.

Affects Windows installations only.

Symptoms

You may see one or more of these symptoms:

1. WProofreader Application Server doesn't start.

2. Requests routed through IIS return 502.3 Bad Gateway because IIS can't reach the application server.

3. Main.log contains repeated entries like this:

Error    Control process failed to connect to main service process. Reason: Client exception. Connection refused. Check logs and ensure sufficient resources allocated.

Solution

Recommended

Upgrade to v6.11.1 or later.

Workaround

Set the AWS_EC2_METADATA_DISABLED=true environment variable and restart the application.

Use this workaround only if you can't upgrade immediately.
