"Server unavailable or unreachable" and websocket connection failure (Docker, Nginx)

manv · July 31, 2024, 4:15pm

Hi all! I’m trying to deploy a JupyterHub instance with Docker (jupyterhub-deploy-docker) and Nginx using a reverse proxy on a machine running Ubuntu 22.

Everything works well for a while until websocket requests start to fail:

Eventually, this leads to a Server unavailable or unreachable message:

I’m sure I’m missing something obvious, but I’ve checked the proposed solutions in the forum without luck. Any ideas?

The only changes to the jupyter_config file from the one in jupyterhub-deploy-docker is:

c.JupyterHub.port = 9000
I’ve also tried c.DockerSpawner.environment.update({“JUPYTERHUB_SINGLEUSER_APP”: “jupyter-server”}) as suggested by @minrk here but it did not fix the problem.

I followed the Nginx configuration suggested when using a reverse proxy:

server {
    listen 80;
    server_name server_url.com;

    # Redirect the request to HTTPS
    return 302 https://$host$request_uri;
}

        listen 443 ssl;

        server_name server_url.com;

I created a new user, created a Notebook and ran some cells, and these are the logs:

Can you share your Nginx logs?

When you see the Server unavailable or unreachable in your browser is your singleuser server still running? Is there anything in the singleuser server logs corresponding to when the connection fails?

If you connect directly to JupyterHub without Nginx does this change anything?

Does it make a difference if you use a different browser/computer/building?

manv · August 1, 2024, 12:48pm

Hi @manics, thank you for getting back to me. I tried many different things without success for a week, which is also the time it takes for authentication to expire for my work VPN (EduVPN). As soon as it asked me to renew my login, the WebSocket errors stopped. Everything seems to be working now.

Your suggestion of trying a different computer/building would probably have helped to figure this out. Thanks!

manv · August 12, 2024, 8:38am

The error seems to be happening again (or still), but only for other users. I’ve asked users to use existing profiles or create their own, and in both cases, the WebSockets eventually disconnect, and they get the “Server unavailable” message.

These are the Jupyter logs of an individual user container between logging in and having to restart their server:

It looks like it’s almost exactly an hour between starting the server and having to restart it. It could just be a coincidence, but maybe it points to some sort of timeout? Have you enabled the idle-culler, or could it be a network or local firewall that terminates a connection after one hour?

Thanks again for looking into it.

Idle culler is not enabled, and I’ve left the connection open on my machine for hours without issue. For some users, it works well both when signing up with their own username and when working with an existing username. For others, it fails in both scenarios within 3-5 minutes.

I’ve even had users with successful connections and some with failing connections while in the same office (on the same network).

Maybe I overlooked something with NativeAuthenticator?

Is it possible to get logs from the user’s container itself that stopped? I know it’s removed after it stops, but perhaps still retrievable if you’ve set up an rsyslog sync or similar. Or if followed with docker logs -f, if it is known what is going to fail beforehand.

The almost-exactly one hour does sound suspicious. It could also be something in the single-user server’s internal idle shutdown mechanisms, if that is configured.

I’m keeping the containers, as I need users to be able to come back to their environments, could that be a problem?

Because it seems (to me) like the issue is with some networks, everything works well in my home network or on the wi-fi in my office. But then it fails in the wired LAN in my office and a friend’s home network. I did get logs of a failed connection, these are for the Jupyterhub container:

Unfortunately, I don’t see anything informative about the error (or even evidence of the error at all). Given that you have a VPN involved, it does seem like that could be related.

It may indeed be relevant that you are re-using containers. They may not restart with all the information they need if anything is changing about the network context. If it’s possible, it’s generally a good idea to not persist containers, and instead use mounted volumes to persist what should be persisted. That makes updates much easier to manage.

Thanks again. I’m working with IT at the office, and they’ve found duplicated packets, or rather packets received by the client that were not sent by the server. So it could be related to Docker, our firewall config or who knows. I’m starting to suspect it’s not Jupyter’s fault.

I’ll update when I know more.

manv · September 6, 2024, 1:25pm

It seems like I finally found a solution, it was network settings.

We traced the packets between client and server and it appears like there is no correct negotiation of the maximum segment size. The server can use a maximum MTU size of 9000 (jumbo frames), but the client cannot, so frames were missing in some networks. Apparently, there must be a negotiation of the maximum transport MTU size between the client and server, which must be max 1500B.

We made sure that Path MTU Discovery (PMTUD) was enabled, as well as MTU:

net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_mtu_probing = 1

I could only solve this with assistance from my colleagues, my network skills are trash. Thanks, @manics and @minrk, for your help.
