I'm getting "Timeout getting IP address " error rancher v1.4.1

getting “Timeout getting IP address” when trying to run any container , most of infrastructure containers are not working now .

any fix or root cause for that ?

This essentially means cross-host networking isn’t working. Check that each host shows up in the UI with a unique IP and that each host can reach every other using those IPs on 500/udp and 4500/udp.

Thanks a lot .

I removed all the infrastructure containers , then I restarted the machines after making sure that the ins are shown in the UI ,

installed the infrastructure containers again one by one , and I can ping from each container to the others now.

I don’t know why the the servers didn’t see each others before .

it happened again , now I don’t know what makes the machines lose the connections to each others after a day . any Ideas ?

@ayman2nov what version of rancher are you running?
Can you grab the logs from the network-manager container and share?
Also, it might be better if you open an issue at https://github.com/rancher/rancher/issues for this.

@cjellick

I did remove all the network related stacks , and reinstall them all again ( The Library stacks ) , and it works for me
