Failed to serve quic connection #510

Closed Barre closed 2 years ago

Barre commented 2 years ago

While running cloudflared using --protocol quic, our origin fails a few times per day with the error:

Nov 17 02:24:46  ERR Failed to serve quic connection, err: failed to accept QUIC stream: timeout: no recent network activity
Nov 17 07:01:42 ERR Failed to serve quic connection, err: failed to accept QUIC stream: timeout: no recent network activity
[...]

When it happens, cloudflared seems to register a new connection. Before a new connection is registered, cloudflare returns 502 - Bad gateway responses while accessing our services.

The exact same thing happens to us ! Any news ?

nmldiegues commented 2 years ago

Can you share the cloudflared logs that evidence the problem, and share the tunnel UUID for the matching logs?

Barre commented 2 years ago

From our side, some more logs:

nmldiegues commented 2 years ago

I think you may be hitting an edge case we have identified --- which should be independent of the transport protocol used to talk to our edge --- and that's being worked on. If that's so, it'll be fixed on our end and you won't have to do anything to get it fixed.

Note that having connections dropping and reconnecting is normal and expected --- particularly if it does not happen with a rapid cadence. What's not expected is for client requests to fail, as long as 1 connection is still up between cloudflared and Cloudflare edge.

Barre commented 2 years ago

Perfect, thank you!

I'll continue monitoring on our end and inform you if the issue persists.

msiherb commented 2 years ago

Same error popped up in our logs too but its not consistent. 70 hits in the last 7 days. In fact it happened only during the following times.

Barre commented 2 years ago

The issue did not occur again for us today.

adyanth commented 2 years ago

I can see this same issue in the logs, and the behaviour is that I see a 524 error on the webpage. A sample Ray ID: 6bd982b7da924aec

ivanjx commented 2 years ago

in my case this happens after i sent many http requests (like seeking through an hls video feed quickly) in a short amount of time then it will give 524. if i switch my network (client device) from wifi to mobile data for example then it starts responding again and if i switched back to the same wifi then it gives me 524 again. so it seems that 524 is tied to one type of connection.

user8446 commented 2 years ago

The errors stopped for me when switching back to http2, so might not be an edge case. Others would have to try http2 to see if this is in indeed quic related.

buroa commented 2 years ago

Same thing happening to me. I had to switch back to http2 because too many eyeballs are getting errors from time to time. It also seems to be a particular connection, not all clients have the same problem. Some can connect and some can't. I have tried to switch to quic many times over the past few weeks but it results in the same stalled connections. It's completely random, but I looked at my graphs and saw this weird spike on one of Cloudflared connections. There definitely wasn't an influx of requests, it just seemed something was stuck.

The tunnel/cloudflared sits inside a k8s cluster, and does scale up and down from time to time. It routes all requests to the Contour/Envoy ingress controller.

I also see these logs:

Failed to serve quic connection error="failed to accept QUIC stream: timeout: no recent network activity" connIndex=2
Failed to serve quic connection error="timeout: no recent network activity" connIndex=2

Tunnel ID: b98a45ec-4647-489c-b57a-93cc9051fcdd

buroa commented 2 years ago

Adding a bit more context here... I think this is due to when a backend issues a TCP RST (or hangs too long)... In my deployment, it is like so:

Cloudflared <-> Contour Envoy <-> Backend

When the backend takes too long to reply, Envoy breaks the backend connection (TCP RST), but Cloudflared doesn't realize it and then the entire flow breaks as well as clients cannot connect (origin timeouts). I even created multiple origin tunnels (Cloudflare Load Balancer) and still, even one connection having this issue will break all origin tunnels.

PSA: If this happens on http2, the Cloudflare Edge terminates the origin connection, which is quite annoying if you have a shell to your server, because that is destroyed as well.

michaelwu0505 commented 2 years ago

I can confirm that cloudflared version 2022.2.0 (built 2022-02-04-1113 UTC) also has this problem. I encountered the same issue a few days ago.

nmldiegues commented 2 years ago

We have done some work/fixes for QUIC protocol transport in both cloudflared and our edge. Would you mind letting us know how this goes with latest cloudflared version 2022.2.2?

ivanjx commented 2 years ago

done some testing with hls streaming and seems to be working better with the latest version. will continue to monitor for a few days

nmldiegues commented 2 years ago

We'll close the issue for now. We'd appreciate a new one being open with new evidence, should it happen, so we do not conflate a lot of confusing evidence in the same thread over a long period of time.

achilles-git commented 2 years ago

@nmldiegues I think you may be hitting an edge case we have identified is it possible to tell what was the edge case here ??

We have done some work/fixes for QUIC protocol transport in both cloudflared and our edge. and what was the fix done at these sides ??

kienzlenator commented 1 year ago

ERR Connection terminated error="failed to accept QUIC stream: timeout: no recent network activity" connIndex=0

This continues to be an issue. I am using the Cloudflared addon with Home Assistant and it is next to impossible to keep my tunnel on line. For the record, I buy my domain directly from Cloudflare so that probably isn't the issue here.

Today i had the same problem, i just changed my default dns IP addresses to the OpenDNS ones and it solved the problem (you could use others like google's or the cloudflare ones)

Rijndael1998 commented 1 year ago

The problem resolved itself. I'm incredibly confused.

I have the same exact problem that @Rijndael1998 mentioned since today. No changes on our side.

@nmldiegues perhaps this could be reopened?

Also got this error Using a Cloudflare domain and the home assistant addon. It started after a power loss and now several reboots and fresh installations still the same. Also in zero trust the tunnel goes to down after i create a new one.

Also experiencing this problem 100% of the time for at least the last couple of weeks. No errors, just connection attempts time out. Running two cloudflared v2023.8.2 instances on VMs running Oracle Linux 8.8.

Same issue 2023-11-14T04:39:53Z ERR Failed to serve quic connection error="timeout: no recent network activity" connIndex=0 event=0

Same issue,

2023-12-07T08:47:34Z ERR Failed to serve quic connection error="timeout: no recent network activity"

The worst part is that the requests are dropped even though the LoadBalancer should retry the requests to a different origin but for some reason, it does not (Zero-downtime-failover feature). Does anyone know why?

Also here. Has anyone solved it?

Still issues on our site..

Connection terminated error="failed to accept QUIC stream

germanikus666 commented 9 months ago

I have the same error. Is there already a solution for this?

schlumm commented 9 months ago

I have changed the domain to xyz instead of cf. After applying all the changes, it started to work. For me, the wifi at my work probably dont allow using the xyz domain, so I need to switch to mobile data.
