Summary

I have set-up a custom base_app_url (e.g. https://cronicle.mydomain.com) but still when I run jobs from cronicle UI I get the following Log Watcher: Server Connect Error: Error: websocket error (https://XXX.XX.XX.XX:3013) error. The error shows an IP address instead of what is configured under my config variable base_app_url.

Steps to reproduce the problem

  1. Update base_app_url with a custom domain
  2. Start cronicle using /opt/cronicle/bin/control.sh
  3. Run a job and see the Log Watcher error out.

Your Setup

Server Environment:

  1. Domain: cronicle.mydomain.com
  2. Server IP: XXX.XXX.X.XXX
  3. Firewall: Configured to allow HTTP (port 80) and HTTPS (port 443).

Nginx Configuration:

  1. Proxying: Nginx proxies traffic to Cronicle on port 3012 with WebSocket support.
  2. HTTPS: Let’s Encrypt SSL certificates are used for cronicle.mydomain.com, redirecting all HTTP traffic to HTTPS.

Cronicle Configuration:

  1. base_app_url: Set to https://cronicle.mydomain.com, ensuring URLs in the app and notifications are correct.
  2. WebSocket and Direct Connect: Configured to use WebSocket transport and indirect connections (web_direct_connect: false) for compatibility with the Nginx reverse proxy.
  3. Storage: Using default filesystem storage for Cronicle data, with logs and data directories under /opt/cronicle.

Operating system and version?

Ubuntu 24.04 LTS

Node.js version?

v22.4.1

Cronicle software version?

Version 0.9.61

Are you using a multi-server setup, or just a single server?

Single server

Are you using the filesystem as back-end storage, or S3/Couchbase?

filesystem

Can you reproduce the crash consistently?

Yes

So sorry about this. Live log watching requires the user's browser to make a direct WebSocket connection to the worker server that is running the job (not the master server).

This doesn't work well for some people with complex network topographies, i.e. situations where the worker servers aren't directly accessible by your users' client machines.

Check out Mike's Cronicle fork over at: https://github.com/cronicle-edge/cronicle-edge

His implementation uses the master server as a proxy for log watching, getting around this problem entirely.

This is also solved in Cronicle v2, coming out in 2025.
