I doubled the size of my cluster adding new nodes on ubuntu 18.04. Installed DSE 4.8.16 from the downloadable binary. Installed java version "1.8.0_211" on the new nodes. Updated the datastax-agents from OpCenter and expected my scheduled backup to s3 to "just work" but it doesn't. Fails on all 6 of the new nodes as shown in the screenshot. I don't exactly know where to begin, whether this is an opscenter config problem or something else. Any help welcome!
