Help viewing the full Samourai Server logs (Whirlpool)

Could someone explain how to access the full logs for the Samourai/Whirlpool Server? The Troubleshooting screen in settings does not provide enough information. Basically I’m having issues with Whirlpool, my mixes are failing with “Technical error, check logs for details”, but I can’t locate the logs.

Thanks in advance!

In case it matters to retrieving the logs, I’m running on an ubuntu server.
