Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/579

Hello,

I install this project on my own server, i don't know if the error i found is an issue or a bad setting.

I install on a VPS debian, apache 2 with a proxy (because there are many vhosts on my server).

i secure sending message with a unique admin user and when i send a message i receive this :

{"code":50001,"http":500,"error":"internal server error"}

But i receive the message on the webapp and android app.

I don't know where logs are, i did not found them in /var/log.

My server settings:

listen-http: "127.0.0.1:2586"
behind-proxy: true
cache-file: "/var/cache/ntfy/cache.db"
attachment-cache-dir: "/var/cache/ntfy/attachments"
keepalive-interval: "45s"
auth-file: "/var/lib/ntfy/user.db"
auth-default-access: "deny-all"

My vhost config :

<VirtualHost *:80>
    ServerName ntfy.mydomain.com

    # Proxy connections to ntfy (requires "a2enmod proxy")
    ProxyPass / http://127.0.0.1:2586/
    ProxyPassReverse / http://127.0.0.1:2586/

    SetEnv proxy-nokeepalive 1
    SetEnv proxy-sendchunked 1

    # Higher than the max message size of 4096 bytes
    LimitRequestBody 102400

    # Enable mod_rewrite (requires "a2enmod rewrite")
    RewriteEngine on

    # Redirect HTTP to HTTPS, but only for GET topic addresses, since we want 
    # it to work with curl without the annoying https:// prefix 
    RewriteCond %{REQUEST_METHOD} GET
    RewriteRule ^/([-_A-Za-z0-9]{0,64})$ https://%{SERVER_NAME}/$1 [END,NE,R=permanent]
</VirtualHost>

and vhost https :

<IfModule mod_ssl.c>
<VirtualHost *:443>
    ServerName ntfy.mydomain.com

    # Proxy connections to ntfy (requires "a2enmod proxy")
    ProxyPass / http://127.0.0.1:2586/
    ProxyPassReverse / http://127.0.0.1:2586/

    SetEnv proxy-nokeepalive 1
    SetEnv proxy-sendchunked 1

    # Higher than the max message size of 4096 bytes
    LimitRequestBody 102400

    # Enable mod_rewrite (requires "a2enmod rewrite")
    RewriteEngine on

    # WebSockets support (requires "a2enmod rewrite proxy_wstunnel")
    RewriteCond %{HTTP:Upgrade} websocket [NC]
    RewriteCond %{HTTP:Connection} upgrade [NC]
    RewriteRule ^/?(.*) "ws://127.0.0.1:2586/$1" [P,L]

SSLCertificateFile /etc/letsencrypt/live/ntfy.mydomain.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/ntfy.mydomain.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
</IfModule>

I believe the problem is between my chair and my keyboard but i need help to understand :)

OK thanks, i did a search but not with the good hit words...

I see there nothing in this ticket to help me and i have a new information

There is no problem when i lauch service with the command line ntfy serve but when the commend is launch on server startup, i receive the error.

I will try to send logs into a file to catch them.

Enable debug or trace logs in the server, and that should tell you what's wrong.

I increase level log of vhost but it was not better.

i used a file in /etc/init to launch service on startup, i change to @reboot job in crontab and it works !
