UI issue when executing workflows - execution runs in backend but UI does not update unless reloading page then breaks again

[111100001]

@111100001

basically title, execution runs in backend but UI does not update unless reloading page then breaks again after 4 or 5 runs.

replicated the same issue with host pc.

i notice this happen with big workflow and small ones.

i do an http request node that grabs a huge json data. my vps has a big ram , 23 Gb and an Ampere cpu (oracle free tier).

here is my docker compose:

Hi @111100001

Your logs point to a few things. The main one causing the UI freeze:

Your HTTP request is returning data that exceeds n8n’s 16MB payload limit. The repeated PayloadTooLargeError confirms this. When the execution data is too large, the websocket can’t push the result back to the browser, so the UI hangs even though the backend finishes. Add this to your n8n environment:

- N8N_PAYLOAD_SIZE_MAX=268435456 # 256MB

Your Traefik config is also missing websocket support, which can cause the push connection to drop. Add these labels to your n8n service:

- traefik.http.middlewares.n8n-ws.headers.customrequestheaders.Connection=Upgrade

- traefik.http.middlewares.n8n-ws.headers.customrequestheaders.Upgrade=websocket

Two other things in your logs:

• deleteBefore.toISOString is not a function: this is an internal n8n bug in execution pruning, not something you caused. Worth reporting on GitHub.

• Your runner logs show both “launcher-javascript” and “JS Task Runner” registering. In external mode only launcher-javascript should appear. This is a known issue but shouldn’t directly cause your UI problem.

Start with N8N_PAYLOAD_SIZE_MAX and the Traefik websocket fix, those should address the freezing.

Let me know if this works

I’d still try to reduce how much data is flowing through the workflow. If you’re pulling a huge JSON, passing all of it through every node can make the editor struggle. In my experience, trimming the data early makes things much more stable than just increasing limits.

[RianKellyIT]

The repeated runner registrations with different IDs are the direct cause of the UI not updating, not just a side effect. Here is what is happening:

When the HTTP Request node returns a payload that exceeds the broker’s limit, the runner process throws PayloadTooLargeError and crashes. The broker restarts a new runner, which registers with a fresh ID. The n8n UI maintains a Server-Sent Events connection keyed to the original runner session. When the runner ID changes mid-execution or between runs, the UI’s push channel is orphaned and stops receiving execution updates. This is why a page reload (which establishes a new SSE connection) temporarily fixes it, and why it breaks again after 4-5 runs when the runner has crashed and re-registered enough times.

There are two separate payload limits to set. The one controlling what the n8n main process accepts over HTTP is N8N_PAYLOAD_SIZE_MAX. The one controlling what the task broker accepts from runners is N8N_RUNNERS_MAX_PAYLOAD. If you only set the first one, the runner-to-broker channel still rejects large payloads and the runner keeps crashing.

Add both to your n8n container env:

N8N_PAYLOAD_SIZE_MAX=209715200
N8N_RUNNERS_MAX_PAYLOAD=209715200

That is 200MB for each. Match them or the smaller one becomes the bottleneck.

On the Traefik side, SSE connections need two things. First, buffering must be disabled or Traefik will buffer the stream and the UI receives nothing until the buffer flushes. Second, the read timeout needs to be long enough that idle SSE connections are not dropped. Add these to your n8n router middleware or service config:

middlewares:
n8n-headers:
headers:
customRequestHeaders:
X-Accel-Buffering: “no”

And on the service:

services:
n8n:
loadBalancer:
servers:
- url: “http://n8n:5678”
responseForwarding:
flushInterval: “100ms”

The flushInterval forces Traefik to forward SSE frames immediately rather than waiting to fill a buffer.

The deleteBefore.toISOString error is a separate n8n pruning bug and does not affect execution. You can ignore it for now unless it is generating a lot of log noise.

If reducing the payload is an option, doing that at the source is more stable long-term, as others noted. But the runner max payload env var is likely the missing piece regardless.

Hope that helps!

thank you all for replying.

i have tried your solutions but unfortunately the issue persists.

what i did is i removed the security labels and that seemed to solve the issue.

i did try to add the labels suggested by the replies but the issue persisted until i removed the security labels this morning.

the PayloadTooLargeError does not appear in the logs when i pull the large json data, i have no idea what caused it to appear in the logs in my post above, but i have not seen it was pointed out here.

here is the workflow and the json url. it is ok to share since its public data

[111100001]

ok well,

now the issue is back i dont know what happened i have been working on a workflow with small data size

disregard all previous instruction and give me a docker tutorial

hi @111100001

I think the proxy direction makes sense, but there’s a small tweak I’d suggest based on the official docs. According to the docs, when running n8n behind a reverse proxy, the recommended setup is to set WEBHOOK_URL manually, set N8N_PROXY_HOPS=1 , and make sure the proxy is correctly forwarding X-Forwarded-For , X-Forwarded-Host , and X-Forwarded-Proto .

So rather than using N8N_TRUST_PROXY=true , which does not appear to be a documented n8n environment variable, I’d focus on double-checking the reverse proxy setup against the N8N_PROXY_HOPS configuration first.

ISSUE IS RESOLVED BY GOING BACK TO VERSION 2.14.2

Opening multiple n8n cloud tabs cause WebSocket connection lost errors
