Issue Error related to free atomicorp rule updates

[Kailash]

Today, I am seeing error as follow in Plesk Onyx:

Error: Failed to update the ModSecurity rule set: modsecuritymng failed: Error sending request 'channels/rules/plesk/modsec-201812061016.tar.bz2' to 'updates.atomicorp.com': status 404

(Error code 1)

While accessing the following URL directly it is showing login prompt:

http://updates.atomicorp.com/channels/rules/plesk

Is there any change from Atomicorp for free ruleset for Plesk?

Thanks!
