I have four instances of Lucee running for four sites.
They were all on 220.127.116.11. I upgraded each one to 18.104.22.168 a few minutes ago - except one. One would not upgrade.
I tried three times.
I restarted the instance of Lucee. Tried again, same error.
I downloaded the core file (.lco) and copied to patches. That updated the version.
Still, want to be able to use the server admin to do this, not sftp.
