Issue Plesk Premium Antivirus will not run when TLS versions and ciphers by Mozilla are set to Modern

[TurnKeyWebsites]

Plesk Premium Antivirus will not run when TLS versions and ciphers by Mozilla are set to Modern.

with the ciphers set to Intermediate (recommended) - Plesk Premium Antivirus runs without error
with the ciphers set to modern - Plesk Premium Antivirus fails with:

"Unable to start service: Unable to manage service by drwebmng: ('start', 'drweb'). Error: /opt/psa/admin/bin/drwebmng[3462]: Unable to start drweb antivirus daemon "

'service drwebd status' suggests the problem is a licensing issue, that is incorrect.

When the Mozilla setting is "Intermediate (recommended)", Plesk is loading old protocols (TLSv1 TLSv1.1) so that's not a secure option.

Is there a workaround for this?
Any idea when Plesk will update the protocol support in the antivirus product?

Thanks

In the meantime Mozilla have updated their definition of Intermediate to more modern values, and now drwebd will not start with the Intermediate settings. Seems to be a problem in drwebd which has just not been resolved yet by Plesk Team.
