Host mode returns connection refused

Hello,

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?

Thanks,
Mr T
