No Connection to Server

[Halllo5]

Hello
I have installed everything successfully, but after opening Outline and logging in I can't edit any documents and after a few seconds I get the error message "connection to server lost".
I use a raspberryPI 4b with 8GB ram
Thanks for the help in advance

I'm having the same issue.

I've set it up on an AWS instance, after install I can create documents, but not modify any of its contents.

The web sockets seems to be failing, and the page shows "connection to server lost".

Edit: I've been able to fix it by following the NGINX guide from the outline docs -- although I'm not sure what exactly fixed it, I had to entirely stop/start my instance before it started working.

@KevinVR hello man, can you please guide me how do you setup using aws on ec2 instance?

@meakshayraut
Im not sure if i can help you but i recently figured out how to set it up using only docker compose/portainer.
The first thing i did was deploy [minio with docker] (https://min.io/docs/minio/container/index.html#procedure) first.
After that I used the following docker compose to deploy outline.

All the {{ }} need to be replaced with the correct value (the same with the same value of course)
Hope I could help, even if it was not what you asked for.

@Halllo5 I'm facing the same issue with the latest version of outline-wiki. Were you able to fix the issue?

[Halllo5]

@kunalgupta022 I actually never figured it out and just switched to manually writing the docker compose. I think I am still using the one I provided in my last comment and it has worked perfectly so far. Otherwise, the documentation has improved a lot, I think: https://docs.getoutline.com/s/hosting/doc/docker-7pfeLP5a8t

[kunalgupta022]

@Halllo5 Realised that there was nginx setup with the zrok link that we were pointing it to (reference).
For anyone in the future who comes across this:

Nevermind, I've found solution. Needed to add these lines to nginx:
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

This fixed it and is documented here by the outline team.
