The issue is that after doing a CA apdpata backup, my system loses Internet access for quite some time (6-12 hours usually) before coming back, it's very weird. the CA appdata backup only takes about an hour to backup.

 

I noticed that I got errors connecting to github to check for updates, and errors connecting to dockerhub to check for docker updates, etc. It has been a weird issue to track down.

 

I am on 6.10.3, and this issue only started after the 6.10.x branch.

I changed from having a docker VLAN to combat the macvlan docker issue, and just used the new ipvlan issue to prevent crashing.

No crashes so far, but now I'm running into this really bizarre issue. no idea if they are related.

 

Everything is totally fine until I run the CA appdata backup, at which point things go offline and I'm unable to connect to the Internet from the server or some containers as well. Very strange indeed. Any help is appreciated.

 

Note, I turned on checking for app updates after an appdata backup, and it hangs there too now.

Here's relevant system log info below that happens when invoking a CA appdata backup. 

 

I am unable to ping known-good addreses, such as 8.8.8.8 or 9.9.9.9 I just get

From 10.0.0.10 icmp_seq=1 Destination Host Unreachable

During a ping test I stopped docker so I could check on some network configs to see if making any changes would resolve the issue, but it looks like just stopping the docker service itself corrected the issue.

 

 

EDIT: Here are my docker settings. Nothing unusual here that would cause this, and again it only seems to happen when I run a CA appdata backup where it stops all containers, backs them up, and then starts them again.

bumping this - hoping someone has an option for me to at least try for troubleshooting this, as it's an odd one to say the least.

Swapped back to macvlan mode w/ a dedicated docker vlan for few containers that need static IPs.

 

so far issue has not resurfaced.

bug report created here.

 

 

This could be potentially related to the issue i have described in the following post:

(maybe this thread is related to your issue.)

This certainly looks like it could be related, for me my network is fine up until I run a CA Appdata backup and then it stops working, very weird. It certainly seems to be ipvlan related for me too!
