Is anyone still using cascading Software Update Server? If yes, I have an issue with it

[carlo_anselmi]

Hello
I am still working with an old High Sierra SUS with remote replicas ("cascading")
After the recent updates released from Apple, the replicas suddendly started showing the below error messages in the logs and obviously don't download some of the updates available on the main SUS, which works perfectly.
Only one of the two 005 Security Updates (the one for Sierra) is available on the replicas, Supplemental update for Mojave #2 is also available.
Both swupd.conf and swupd.plist have the right catalogs for Mojave and I have already deleted all the relevant files (catalogs and downloads folders on the replicas)
Any suggestion? (and yes, I am already considering moving to NetSUS :-)
Thank you all
Carlo
