Troubleshooting

Common issues and steps you can take to fix them.

General Issues

Feature(s) Stopped Working After Updating to Latest Version

Your browser might have cached an older version of a JavaScript(JS) file which is no longer compatible with the current version of LubeLogger. Try the following steps:

  1. Verify - Try navigating to LubeLogger in Incognito mode.
  2. If everything functions as expected in Incognito, you have a caching issue.

3. Clear your browser's cache or perform a hard reload(hit CTRL+SHIFT+R multiple times on most browsers)

Can't Send Email via SMTP

Note that for most email providers, you can no longer use your account password to authenticate and must instead generate an app password for LubeLogger to be able to authenticate on your behalf to your email provider's SMTP server.

If you've downloaded the .env file from the GitHub repo, there is an issue with how the file gets formatted when it is downloaded, you will have to copy the contents and re-create one manually on your machine.

Gmail SMTP Authentication Error

Use port 587 instead of 465, LubeLogger only supports TLS.

Console shows Authentication Errors

Those are purely informational, add this line in your environment variables to prevent information logs from showing up in the console.

LOGGING__LOGLEVEL__DEFAULT=Error

Locale Issues

Can't input values in "," format / shows up as 0.

Ensure that your locale environment variables are configured correctly, note that if running via docker, both environment variables LANG and LC_ALL have to be identical.

Locale Not Updating/ยค Currency Symbol/Date Format Issues

Try the following steps:

  1. Check if the environment variables are injected correctly(does SMTP/OICD configurations work)
  2. Re-deploy Container
  3. If that doesn't work, try re-creating the .env file
  4. If using Portainer/Synology, you might have to enter the environment variables manually.

5. One last thing to try: copy and paste the environment variables into docker-compose.yml

Postgres Issues

Schema Does Not Exist

Make sure that there is a schema named "app" in the database as specified in the Postgres connection string. For more information, see Postgres

OpenID Connect(OIDC) Issues

No Option to Login via OIDC

Make sure Authentication is enabled, check "Enable Authentication" in Settings tab and set up root user credentials

Logging-in via OIDC Requires Token

LubeLogger operates on an invite-only basis, a token will need to be generated for the user logging in via OIDC if it is their first time. Once an account for the user exists they will no longer be prompted for the token in subsequent login attempts.

No Auto-Redirect to OIDC Provider

A LogOutURL must be provided for the OIDC provider otherwise the OIDC login flow will not be auto-initiated.

Expected id_token, received {...}

Add openid to the OpenIDConfig__Scope environment variable

Server Issues

ERR_TOO_MANY_REDIRECTS

If you encounter this error in your browser while attempting to navigate to your LubeLogger instance and it is accompanied by the following console error in your Docker Container:

The configured user limit (128) on the number of inotify instances has been reached

You have reached the maximum limit of file watchers across all your Docker Containers. In LubeLogger, file watchers are crucial for detecting changes to configuration files. To fix this, you will need to increase the inotify limit above 128.

API Issues

Input Object Invalid

This error is either caused by a missing field in the input object or if the API client is passing the payload in as json. If all fields are already provided, check and make sure that the payload is passed in as either form-data or x-www-urlencoded

Can't Access LubeLogger Instance from Other Devices

This problem is specific to the Windows Standalone Executable, the problem stems from the fact that Kestrel is configured by default to listen on and only on localhost. In order to get around this, you will need to retrieve the IPv4 address of your local machine, and add the following section into appsettings.json

Note: replace 10.0.0.4:5000/5011 with your local ip address and port

"Kestrel": {
   "Endpoints": {
     "Http": {
       "Url": "http://10.0.0.4:5000"
     },
     "Https": {
       "Url": "https://10.0.0.4:5011"
     },
}

Additionally, see Setting up HTTPS for HTTPS/SSL Cert Configuration

NGINX / Cloudflare

LubeLogger is a web app that runs on Kestrel, it literally doesn't matter if it's deployed behind a reverse proxy or Cloudflare tunnel. As long as the app can receive traffic on the port it's configured on, it will run.

Here's a sample Nginx reverse proxy configuration courtesy of thehijacker

server
{
    listen 443 ssl http2;
    server_name lubelogger.domain.com;

    ssl_certificate /etc/nginx/ssl/acme/domain.com/fullchain.pem;
    ssl_certificate_key /etc/nginx/ssl/acme/domain.com/key.pem;
    ssl_dhparam /etc/nginx/ssl/acme/domain.com/dhparams.pem;
    ssl_trusted_certificate /etc/nginx/ssl/acme/domain.com/fullchain.pem;

    location /
    {
        proxy_pass http://192.168.28.53:8289;
        client_max_body_size               50000M;
        proxy_set_header Host              $http_host;
        proxy_set_header X-Real-IP         $remote_addr;
        proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade    $http_upgrade;
        proxy_set_header   Connection "upgrade";
        proxy_redirect off;
    }
}
