If I read https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/rancher-v2-7-3/ correctly, 1.26 is not yet supported by the newest version of Rancher. I seem to recall that 2.7.2 was the first version to support 1.25 (with PSPs going away it was a big change), so definitely Rancher older than that wouldn't be able to handle 1.26. Newest might handle it and just not have gone through all certification tests yet or just have an odd edge case issue or two or it might have more severe problems. Hard to say with it not being officially supported and me not working for Rancher.
