Connection timeout to all services #1

Closed psravikiran closed 2 years ago

psravikiran commented 2 years ago

Hi, I am trying this on Ubuntu 20.04. Getting connection timeouts to mongodb and probably between all the services.

Please give some clues on how to solve

Can you verify if you can ping between namespaces? e.g. from smf to upf. If you can't it looks like bridge is not forwarding packets

I had similar issue once, solved it by following this: https://serverfault.com/questions/963759/docker-breaks-libvirt-bridge-network

Thank you.. Just setting this after the env-init solved the issue.

sysctl -w net.bridge.bridge-nf-call-iptables=0
