Dear ​,

I would recommend to remove the feedback file from this post and wait for the information from support.

If it is urgent, please call support.

A feedback file contains sensitive data and should therefore not be posted into the community.

Please also note that due to https://community.mcafee.com/docs/DOC-4823#jive_content_id_Prerequisites you should ensure that all Proxy in the Central management should run the same version.

A central management with 7.2, 7.4 and 7.6 will not work.

Regards,

Katharina

how i remove the attachment

"A central management with 7.2, 7.4 and 7.6 will not work." -> E.g. 7.4.1 moved the location where the license file is stored in the storage... which could be the cause of what you see. Katarina is correct: you should not run versions with such a huge difference in version numbers in a cluster. That's really a bad idea.
