WebSocket gives error 405 on CloudFlare

[KristinnVikarJ]

I've been trying to setup CTFNote on my server, but everytime I try to open a pad for any task it simply opens an iframe of the index page.
Only change I've done was change the port from 80 to 8080

Hello,

I've been trying to setup CTFNote on my server

What branch/commit do you use ? How do you start CTFNote ?

Only change I've done was change the port from 80 to 8080

Please, send the output of git diff. Here is what it should look like :

But changing this in the newest commit causes the grahpql websocket to freak out
I have cloudflare set up to handle the ssl stuff for me, the request seems to go through but the websocket instantly closes with an error saying "Unexpected server response: 405"

I have cloudflare set up to handle the ssl stuff for me

I do not use CloudFlare, but I know that some team deployed CTFNote with it.
I don't think this is the problem. Can you try without CloudFlare just in case ?

But changing this in the newest commit causes the grahpql websocket to freak out

Can you be more specific about what "to freak out" means ?
Ideally, we'd like to see the output of your browser's console.

Can you try with tag v2.0.1 ?

Assuming you have no data yet :

docker-compose down -v # This destroys the database !

git checkout v2.0.1
docker-compose build --pull
docker-compose up -d

sleep 5

docker-compose top
docker-compose logs front api

This should print the following list of processes (or equivalent)

After switching from cloudflare and using certbot it works completely fine
It's weird because a project I'm working on that uses wss (where cloudflare handles the cert) has no issues with it

The websocket used to (on chrome) spam empty errors, but on microsoft edge it gave an actual error saying "Unexpected server response: 405"

But after completely restarting the installation after the recent updates its all working perfectly

Later I had some minor issues where I was unable to migrate properly because docker-compose exec refuses to give me any output so I had to tell everyone to re-register on the website but that's not too big of a deal.

[XeR]

Hmmm… this is quite surprising ! 405 is "Method Not Allowed".
I'll keep this issue opened and change its title in the hope of catching the attention of those who have the same problem so they can join the conversation. :-)

Hi,

Have you tried this:
