Since I updated to 19.03.8, host network is not working anymore for containers using host network. It returns connection refused. Removing host and binding ports fix the accessibility for I need host network for some containers that need network access.
I cannot find anything related to that in the release notes.
Does anyone saw this problem?
I am using swarm btw.
EDIT: reverted to 19.03.5 did not fix the problem. So it’s related to the last update of Ubuntu 18 LTS but not sure what. iptables looks correct.
Anyone has an idea?
