Do your nodes have ipv6? Rancher doesn’t have support for ipv6 and I’ve seen this error commonly occur when people have servers with ipv6.
I’m having the very same issue. It happened after using an out-of-band rescue system on my dedicated box. Afterwards I see some interfaces on ifconfig have ipv6 addresses.
Then I tried disabling ipv6 using sysctl [1]. Reboot. ifconfig shows no trace of ipv6, but Rancher keeps restarting things and ignoring my commands to “Stop” and even “Remove”.
It’s ok with IPv6 not being supported. But hanging like this, it’s just weird…

[1] these options
# IPv6 disabled
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
IPv6 is disabled but no change.
