Unable to create logger and LogViewer doesn't works

This definitely looks more like a network/proxy connectivity issue than a test execution issue.

A few things you should check:

1. Proxy/VPN blocking Katalon services

Try:

  • Disconnecting from the VPN temporarily (if permitted by your organization) and rerun the test.

  • Running from a different network (for example, a mobile hotspot).

If the issue disappears outside the corporate network, then the VPN/proxy/firewall is likely blocking a required Katalon service.

2. Verify that Katalon endpoints are allowed

Ask your network/security team to verify access to Katalon services such as:

If these services are blocked, you may experience:

  • “Unable to create logger” timeout errors

  • Blank Log Viewer

  • Missing user/workspace information

  • Analytics/TestOps/TrueTest related connectivity issues

All communication is typically over HTTPS (port 443).

3. Check Proxy configuration in Katalon Studio

Go to:

Windows-> Katalon studio Preferences → Proxy

Verify that:

  • Proxy host and port are correct

  • Authentication settings are configured if required

  • PAC file settings (if used) are valid

4. Clear workspace cache

Workspace metadata corruption can occasionally cause logging and UI issues.

Try closing Katalon Studio, backing up the project, and clearing the workspace cache before reopening the project.

5. Check the detailed stack trace

The most useful information will be in:

.metadata/.log

Look at the lines immediately following:

Unable to create logger. Root cause (Operation timed out)

The full stack trace often reveals the exact hostname, endpoint, and port that Katalon was attempting to reach when the timeout occurred.

6. Verify HTTPS/WebSocket filtering

Some enterprise proxies allow standard HTTPS traffic but block WebSocket connections. Since the Log Viewer relies on live communication, ask your network team whether HTTPS/WebSocket traffic to Katalon services is being filtered or inspected.
