did I break it…
sudo docker logs --tail 20 storagenode

These are usual long tail cancelation errors, your node loosed the race for pieces. Please search for “tcp fast open” only.
I just tried to activate it if someone could confirm me
I have an error when I run the docker command, I don’t quite understand why…
And the commands below return nothing to me
$ netstat -s | grep FastOpen
$ netstat -s | grep TCPFast
/etc/sysctl.conf file
--sysctl option must be BEFORE the image name, since it’s a docker option, not the node.

Correct, thank you
And aside from this line, is there any other way to confirm that the traffic is going through tcp fastopen?
If it isn’t, you will not see this line.
Yet nothing returns to me

Debian with docker you have to start with 'docker run -d --restart unless-stopped --stop-timeout 300 --network host '
note the ‘–network host’ without TCPFastOpen doesn’t work. I think someone posted about the same thing for Synology.
I believe you mean the reverse - the TCPFastOpen feature doesn’t work without --network host on Debian?
Because --network host does work independently of TCPFastOpen, but you should be aware that switching to the host network exposes all ports of the container to the host.
In case of running multiple nodes you will need to change every port in the second and next nodes to unique ones, as if you were setup them as binary versions.
Same with me sorry to say. But some nodes return the message: TCPFastOpenCookieReqd: 16
when adding --network host i get this error
WARNING: Published ports are discarded when using host network mode

You don’t need the sysctl command. Just use host network, and make sure fast tcp is enabled on the host, and use the host network.

so like this by removing line –sysctl net.ipv4.tcp_fastopen=3
$ netstat -s | grep FastOpen
TCPFastOpenPassive: 15
TCPFastOpenPassiveFail: 18
finally a result!

You don’t need to specify those ports if you use network host.

I tried on iPhone/Safari, but it just shows the link to the forum. The only way to link something is to long-press on the topic’s title and link the entire topic. I saw others linking the exact post, but maybe it works only on PC…

I know about that button; I don’t know what I was doing wrong, but now, after this state-of-the-art explanation, it works flowlessly. 
Thank you for +1 to my knowledge level.

After 20 days of enabling TCP fastopen, I don’t see any difference between traffic.
Synology1, TCPf off, 7.09TB - 314GB egress, 634GB ingress.
Synology2, TCPf on, 6.68TB - 303GB egress, 635GB ingress.
