Mastodon Terminal not starting

[smilebasti]

Hi, i just installed Mastodon successfully. After i created an user on the running server i tried to add the user the admin functions through the Terminal.

The Terminal says: 'Connecting...' and 'If you resize the Window press cntrl+D....'.

After that the screen switches to full black terminal. I have also tried recovery mode but nothing different. I also had a look in the logs but i found nothing..

Thanks ahead for your help

@smilebasti Usually, it will keep saying 'Connecting...' only when the app is not running. Maybe the app was just starting up? Does it say 'Running' in the apps view?

@girish Hi thanks for the fast reply.

Yes the App in running mode.
It is saying 'connecting...' only for a second or two with the screen size and then is all going black (terminal)

[girish]

@smilebasti Do you see this with all apps or just mastodon?

[smilebasti]

@girish This is also with Nextcloud (all other)

@smilebasti Could be one of two reasons:

1. docker is not working for whatever reason. Can you check if you can do something like docker exec -ti mysql /bin/bash on the server ? Does it give you a shell? If not, this is a docker issue which we can debug further based on the error message.

2. Maybe some browser issue. But this seems a bit unlikely. Can you try another browser just in case some extension is causing some problem?

[smilebasti]

@girish Ok the 2. thing is also not working.

1. your command worked fine.

Can you tail -f /home/yellowtent/platformdata/logs/box.log and see if there is some crash/error when you open the terminal view? Any errors in the browser console?

[smilebasti]

Thats the Error i get when i am starting the terminal

<I deleted the image because it showed the domain name - girish>

[smilebasti]

This is the chrome console error

website erased

@smilebasti Indeed, there is a crash in cloudron in quite a strange place. That function should always be defined. Can you send us a mail to support@cloudron.io after enabling ssh access (Support -> enable remote support)?

[girish]

OK, we found that the issue was related to having a reverse proxy in front of Cloudron. This reverse proxy was not configured properly to forward web sockets.

For nginx, we need something like this:

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

server {

    ....

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;
    ...

}

For apache, we need something like this:

  RewriteEngine on

  RewriteCond ${HTTP:Upgrade} websocket [NC]

  RewriteCond ${HTTP:Connection} upgrade [NC]

  RewriteRule .* "wss:/192.168.20.12/$1" [P,L]

For the moment, one can just use SSH to open a web terminal like this:

docker ps -f label=fqdn=app.domain.com

docker exec -ti <containerid_from_above> /bin/bash

@girish I have similar issues, I’m using the nginx proxy manager. Everything works but the app terminal. Already tried your config for ngix but didn’t work.

[girish]

@alwynispat Could be because websocket is not getting forwarded properly via the proxy manager. Does it work without the proxy manager?

[alwynispat]

@girish found the culprit, NPM was not forwarding the web socket properly. Fixed that and the terminal works now.

[girish]

@alwynispat do you mean nginx? How is NPM involved here?

edit: oh, maybe you mean your nginx proxy manager?
