Have you checked this?

Manual Update Action Required by the Administrator
When updating to Zammad 6.0 from a previous version, the system administrator needs to add some content to the configuration of the reverse proxy.

Example for Apache:
ProxyPass /cable ws://127.0.0.1:3000/cable

Example for nginx:
location /cable {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header CLIENT_IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 86400;
proxy_pass http://zammad-railsserver;
}

This is required to enable the new Rails Action Cable based realtime communication. You can find more details about this change at this github commit.

Hello ecomsilio,
I did not do an upgrade but from scratch with docker compose up -d.
Your mentioned changes are already in the last version from my point of view.
on my verison it is already configured under /etc/nginx/sites-enabled/default.

what would be the correct way to fix this error with docker compose?

I have done a test with a VM and the error does not occur there

here is a picture of the error when i call it up on mobile

Same issue like this thread technically:

5

I only have the problem when I want to use mobile on phone or tablett.
also with the test http://myzammadinstance.tld/mobile produces the same error
Using it on the PC works without any problems

No, the websocket won’t work still.

7

Perhaps I expressed myself incorrectly before.

I have a setup with zammad as Docker compose that has the error when I access it via mobile.

another setup with ubuntu 24.04 apache2 and zammad does not have this error when I access it via mobile.

who can provide me with updates on this?

Update from my site:

only when I use a mobile phone or for testing or “https://myinstance.tld/mobile” in the desktop browser do I get the error

in the zammad-railserver-1 console logs i can see this entry:

E, [2025-01-30T16:30:07.004093#1-253120] ERROR – : Failed to upgrade to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: Upgrade, HTTP_UPGRADE: )

on the zammad nginx container i can see this in the log:

    • [30/Jan/2025:16:26:00 +0100] “GET /cable HTTP/1.1” 404 14 “-” “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/132.0.0.0 Safari/537.36”

When I log in on my mobile device, it works without any problems, but there is nothing else I can do. neither create a ticket

@ecomsilio yes, but i didn’t do an update but started over and used the latest docker-compose

Hi Community,

yesterday i have tested a new setup with docker-compose.
i have changed in den docker-compose.yml file the Version from
6.4.1-29 to 6.4.1-32 and another test to 6.4.1-41 but allways the same failure.

What could be the error?
Does anyone have any ideas?
