iManage Plugin ERR HTTPS 401

Provides a fix for the ERR_HTTPS_401 error occurring with the Foxit plugin for iManage.

Answer

Resolving ERR HTTPS 401 Error in iManage PluginProblem Description

Users encounter an "ERR HTTPS 401" error when attempting to log into iManage through the Foxit PDF Editor plugin.

Root Cause

The ERR HTTPS 401 error is typically caused by Windows FIPS (Federal Information Processing Standards) mode being enabled on the client machine. When FIPS mode is active, it enforces strict cryptographic standards that can interfere with the iManage plugin's authentication process.

Solution Steps

Follow these steps to resolve the issue:

Step 1: Check FIPS Registry Setting

  1. Press Windows + R to open the Run dialog
  2. Type regedit and press Enter to open the Registry Editor
  3. Navigate to the following registry path: 
    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy
  4. Locate the "Enabled" entry in the right panel
  5. Check the Data value for "Enabled"

Step 2: Disable FIPS Mode (if enabled)

If the "Enabled" Data value shows "1":

  1. Double-click on the "Enabled" entry
  2. Change the value from "1" to "0"
  3. Click OK to save the changes
  4. Close the Registry Editor

Step 3: Restart and Verify

  1. Restart the computer completely
  2. After restart, return to the registry location and verify the "Enabled" value remains "0"
  3. Launch Foxit PDF Editor and attempt to log into iManage

Step 4: Test the Connection

Try logging into iManage through the Foxit PDF Editor plugin to confirm the issue is resolved.

Important Considerations

Operating System Differences

Organizations may have different Group Policy settings for Windows 10 and Windows 11:

  • Windows 10: FIPS mode may be disabled by default
  • Windows 11: Some organizations enforce FIPS mode as a security requirement

Security Implications

Before disabling FIPS mode, consider:

  • Check with your IT security team about organizational policies
  • Understand that FIPS mode provides enhanced cryptographic security
  • Ensure this change aligns with your organization's security requirements

Current Limitations

The current iManage10 plugin is only compatible with systems where FIPS mode is disabled. This is a known limitation that affects the plugin's ability to authenticate properly when strict cryptographic standards are enforced.

Future Outlook

This incompatibility issue has been escalated to the development team for resolution in a future plugin update. Users experiencing this issue should monitor for plugin updates that will provide FIPS mode compatibility.

Alternative Solutions

If disabling FIPS mode is not possible due to organizational security policies, consider:

  • Using alternative methods to access iManage (web interface, other compatible applications)
  • Contacting your iManage administrator for additional workarounds
  • Waiting for the upcoming plugin update that will address FIPS compatibility
