Same here. I run 2 servers. One upgraded and worked perfectly. The other one I had to completely remove and reinstall. Then worked perfectly too. More a paladin config issue I think. Great work!!
I removed --user 99:100 from extra parameters. First backup worked, subsequent failed. Same as Scridgeon's description. Also version and host name now working
Im running rwo servers. One is v1.1 and nil issues. The other I forced update to V1.2.2 and just will not backup. Have tried pointing to dockersoet IP rather than dockersocket:2375. V1.2.2 does not show unraid version
