How to get logs was right in the thread template when you created this https://wiki.servarr.com/sonarr/troubleshooting#logging-and-log-file
Additional Information:
- Information on the log files is here: https://wiki.servarr.com/sonarr/troubleshooting#logging-and-log-files
- Make sure debug logging is enabled in settings
- Post the log file, not a line or two, or just the error from the Logs table
- Post the full log to hone of the sites recommended in Logging and Log Files section of the wiki
- Do not post them directly here. Post in .txt not .doc, .rtf or some other formatted document
Additionally, latest is not a version. Please always provide the number (and any other details as asked, like OS of the machine that is running Sonarr).
7979 is a non-standard port for Sonarr. Did you change it? You can check in Sonnar Settings > General
And is 192.168.1.20 the correct IP of the machine that is running Sonarr?
