MWG7: WebUI no access !

Jump to solution

Hi all,

our customer got the following error message when trying to access the MWG webui.

Note: /etc/init.d/mwg restart and server reboot did not solve the problem!

Issue while trying to connect to McAfee Web Gateway server.
Please restart MWG (/etc/init.d/mwg restart) and reload applet.

Re: MWG7: WebUI no access !

It seems that the GUI failes while loading the configuration data, which could mean that there is one of the XML files broken. I don't think the output is enough to tell which file may have a problem, so I recommend to file a service request with tech support and provide a feedback to them.

You can execute the feedback via SSH since the GUI is down.

Oh... cool! :-)


Somewhere around here is a thread that explains how to send out an eMail if the hard disk is 90% utilized. Unfortunately disk full is still a common-issue, maybe you want to think about implementing a warning eMail for all your customers, to prevent this issue.

I am glad you were able to solve the problem.

Best,

Andre
