Put Collabora Behind Nginx Without Breaking WebSockets
Configure Nginx TLS termination, Collabora routes, and WebSocket headers, then test the public endpoints before opening real documents.
Measure the rice with the rice measuring cup that comes with the pot (eg, 4 cups of rice), wash it. Put the rice in a pot and fill with water according to the standard water level (4 cups of rice respectively at water level 4 in the White rice / White rice section).

Plug in the power, close the lid and press the Cook button, the White Rice button light lights up.
Rice is cooked, the display panel shows 0 o'clock, the button light Keep Warm is on, switch to keep warm mode, open the rice lid and enjoy.
When you do not want to keep rice warm, press the Cancel button to turn off keep-warm mode.
Configure Nginx TLS termination, Collabora routes, and WebSocket headers, then test the public endpoints before opening real documents.
Trace a 10-minute CODE disconnect to its proxy, load balancer, or WebSocket path, then correct the timeout and verify the session stays connected.
Install the official Collabora Helm chart, configure WOPI access and ingress affinity, and verify the deployment without common setup mistakes.
Use browser requests, WOPI logs, and targeted proxy checks to find why Collabora opens a blank document—and choose a fix that fits the evidence.
Configure CODE Docker dictionaries and tag document passages correctly so English, French, and other supported languages receive the right spell-checking.
Adjust the per-view inactivity threshold in coolwsd and distinguish it from background-tab dimming, document unloading, autosave, and login expiration.
Stop scheduled CODE update checks, review optional remote services, and use outbound network controls without breaking document editing.
Enable secure document editing in Seafile by configuring Collabora’s discovery URL, HTTPS, and WOPI access for your deployment.
Test the system clipboard, adjust browser permissions, and identify when an embedded Collabora integration needs an iframe policy change.
Mount font files into Docker and Collabora’s systemplate so custom typefaces appear in the editor and render correctly in documents.
