Im running zero to jhub on eks.
when saving large notebooks (~50 mb) the corresponding /api/contents/Huge.ipynb?content=0&1619793 HTTP put request fails with connection reset (after something like 1 minute).
running on a better network the request takes 40sec and file is saved properly
When saving on The Littlest JupyterHub (on the bad network) request succeed after 2 minutes while on zero to jhub i get connection reset after 1 min.
This led me to think this is some sort of timeout issue, so i have increased timeouts for every component i could think about (the aws load balancer, the configurable http proxy,)
I saw there was an issue regarding getting connection reset on kubernetes as a result of INVALID packets that are not dropped
(see: kube-proxy Subtleties: Debugging an Intermittent Connection Reset | Kubernetes). i tried to configure conntrack to be liberal but that didn’t work either.
Thnx a lot!
