When you disable a parent rule set on the policy tree of the Web Policy page, its child rule sets are also disabled, which means they are not processed either and their on/off toggle switches are deactivated. You cannot enable a child rule set then without first enabling its parent rule set again.

This works as expected now after there had been issues with it, for example, when a child rule set was opened, but its parent rule set had not been opened before.

Skyhigh CASB uses the Google Reports API to monitor user activities for files in Google Drive. On the Skyhigh Activities page, the file size associated with Google Drive activities appears as -- or -1B based on the following file types:
  • Non-native Google Drive files. File size for non-native files (PDFs, images) appears as -- because the API response does not include file size details for non-native files
  • Native Google Drive files. File size for native files (Docs, Sheets, Slides) appears as -1B because Skyhigh CASB retrieves the file size for native files as -1 from the API response.

FIPS was getting enabled by default even though it was disabled post CC upgrade. This issue was found in the older version of CC below 6.4.0, which is now fixed with the below updates:

  • If your CC version is below 6.4.0, FIPS will be enabled on CC by default. To disable FIPS, see Disable FIPS on CC.
  • After upgrading CC to 6.4.0 or above, you must execute the CLI command to enable or disable the FIPS. For details, see Disable FIPS on CC. When CC version is 6.4.0 and above, the CC preserves the FIPS status, and no manual intervention is required to update its status.

When you log in to Skyhigh CASB, you may encounter the SMTP server port value displayed as 25, instead of the port value configured in the Custom SMTP Server. This issue has been identified for users who log in to Skyhigh CASB for the first time and it is due to the SMTP server being cached with the default value of 25.

As a workaround, the system automatically restarts the CC service (shnlps) in Linux or Unix only if the currently open file connection is greater than or equal to 95 % of the ulimit. The fix is given based on the number of open file connections, so the lsof utility must be installed on Linux or Unix OS.

► How to install lsof utility?
The commands vary for different OS types. For example, if your OS type is UBUNTU, then use the following command to install lsof:

Issue: ePO Reports Failures when Pushing DLP Policy/Classifications to Skyhigh.

Recent fixes and enhancements in Skyhigh Cloud have enhanced the verification process applied when a new policy/classification file is received from ePO. In some circumstances, this process can cause the push from ePO to fail.

The failure is generally caused by classifications being in use in Skyhigh CASB or Web DLP Policy and not present in the content being pushed from ePO, or by EDM training data referenced by ePO classifications not being present in the Skyhigh CASB enhanced EDM fingerprint list.

Resolution: Verify that all classifications present in cloud policies are present in ePO.

Classifications are identified by an internal ID and not by name, so identifying where the policies which require amending/disabling can be difficult to identify. The ePO Orion.log file will show some information regarding the failure, which for these cases will show “409 Conflict”.

Skyhigh Support are able to access internal logs to determine the precise cause of failures.

Issue: In ProxyHA or Transparent Router mode, when a node previously marked as Director is set as Scanner and the configuration is saved, the resulting node fails to become a Scanner node. The hastats tool shows this node as Redundant Director instead of Scanning node.

Workaround: When a node previously marked as Director is to be changed as Scanner:

  1. Set the director priority to 0 and set it as the scanner node. Save the changes.

  2. Log on to the SWG back-end of the corresponding node and execute the command service haproxy stop.

  3. Configure the IP in the HTTP and FTP proxy listeners as 0.0.0.0:<port>.
    For example, change 192.168.20.10:9090 to 0.0.0.0::9090.

  4. Save all changes.

Solution: Upgrade to 8.2.1.

Issue: Transparent Router Mode plus IP-spoofing Performance drops. In the transparent router mode, if IP spoofing is enabled, a high response time (>250 ms) and connection error is observed.

Workaround: Perform the following steps every time any proxy-related configuration is updated from the GUI-based manager.

  1. Locate and open in a text editor of your choice the file /etc/haproxy/haproxy.cfg.

  2. Search for the string frontend fwd_proxy.

  3. Under that block, after the line bind <ip>:<port> accept-proxy transparent, enter the new line maxconn 50000.
    For example:
    bind 192.168.20.150:80 accept-proxy transparent
    maxconn 50000

  4. Repeat this process for each instance of the string frontend fwd_proxy, adding the new line under the accept-proxy transparent entry.

  5. Save and close the file.

  6. Restart the service. Type service haproxy restart and press Enter.

Issue: In the transparent router mode, when only the HTTP proxy is enabled and IP spoofing is enabled only for HTTP traffic, the HTTP connection fails with a 502 error.

Workaround: Enable the FTP proxy. Enable the FTP port redirects and FTP listener configuration at the same time.

Issue: In 8.2, the bandwidth throttling feature in router mode isn't fully supported. Using the feature in the router mode might not throttle the traffic according to the configuration. Existing customers using this feature in the transparent router mode in older releases are advised to not upgrade to the latest version.

Issue: When you update SWG from a version earlier than 7.7.2.14 or with the AV rollback flag (ud-rollbackGAM2015) enabled, SWG 8.0 can't load the old GAM2015 libraries. Instead, it downloads the new engine in the background. This process can take several minutes, depending on your download speed. Users see the error below:

Cannot Load Anti-Malware Engine The Anti-Malware engine could not be loaded and your administrator doesn't allow to deliver content without being checked for viruses.
Please call your administrator with the error message below.

Solution: Don't redirect traffic to SWG before the AV engine has finished all updates. You can view the update status in the SWG dashboard.

Non-critical Known Issues

Issue: In the HAProxy mode, when using the Virtual IP address, the settings for connection timeouts configured in event enable proxy control are ignored. 
The HAProxy only relates to general timeout settings.

Workaround: Increase the general timeout settings in SWG or increase the timeout on the remote site.

Issue: You intermittently see an antimalware engine update error:
[AV] [UpdateFailed2] Error updating the Antivirus engine. Reason: 'Error starting engine 'Skyhigh Gateway Anti-Malware', error code: 5'."
You also see that service restarts take upwards of 40 minutes rather than the expected 5 minutes.

Issue: Spanport Automation stops receiving information from the ICAP server. You can't view log entries in access.log on the spanport proxy.

SWG 9.2.25

Found Icon with Text.png

Issue: 9.2.25 uses an updated version of Tomcat.
This new version of Tomcat causes SWG to suffer an incompatibility with the authentication method "client certificate authentication."
This authentication method is only available when using the SWG UI as a Java Applet (logging in via the browser login page).
Detailed information about client certificate authentication can be found on the About Client Certificate Authentication.

NOTE: Most current browsers don't support Java Applets.
The most notable browser still supporting them is the old Internet Explorer 11, but this is now End of Life.

You see the following entries present in the log file /opt/mwg/log/mwg-errors/mwg-ui.errors.log:

[ERROR] Cannot determine if client certificate is enabled due to implementation changes in Tomcat: java.lang.NoSuchFieldException: endpoint

Issue: After you reboot, the kdump service fails to start.
The current kdump service included in SWG isn't compatible with the latest kernel upgrade provided as part of the Sept 20, 2022 releases.
The kdump service handles kernel failures that occur and recovery from these issues.
When this service is non-functional, kernel failures cause the appliance to become unresponsive, and a manual power cycle is needed to get the appliance back to a working state.

Workarounds: You can avoid the issue on installation and prevent the kernel package from being upgraded.

NOTE: This workaround is only applicable to the CMD method of upgrade.
Instead of running yum upgrade yum && yum upgrade, run yum upgrade yum && yum upgrade --exclude=kernel* -

If you've already upgraded, edit the config files and allow the appliance to recover from the kernel failure and automatically reboot after 5 s:

  1. Edit the sysctl.conf file from the SWG-UI.

  2. Add the line kernel.panic=5 outside the autogenerated block.

  3. Save your changes.
