I am getting these errors after trying this config:

Error: 404 (500)

It's a popup in the middle of immich page as soon as i load it.
(it's working fine in subdomain at the same time)

probably incompatibility with new immich version, have not updated yet, will look into it

now compatible with immich v1.97.0

broken again for v1.98 :(

can you provide more details? when does this error occur?

v1.98.2 works mostly fine for me. only thing that does not work is the websocket connection, upstream did something that prevents the connection, and it's pretty annoying to debug :(

lol sorry - I left it out since it's the exact same as aveexy, as soon as I load up the app

Strange though, I'm on 1.98.0 since that's the latest on docker and getting the error

i've just updated the gist. added some fixes for the websocket connection. nginx completely loses it as soon as encoding headers are present and drops the connection upgrade headers needed for websocket protocol switch.

it might be necessary to delete all the cached files in /var/cache/nginx/immich_revprox

Does anyone have a config for Apache?
Edit: Never mind, switched to using a subdomain.
