I've recently upgraded FusionPBX from 4.5 to 5.1.1 (11df74853a52524fc13de66c65a8b46e479a8349). I went through every step in Advanced -> Upgrade one-by-one. I have a voicemail box set to Voicemail File: Download Link (No Login Required). This includes a download link the voicemail email notification that allows the message to be downloaded without a login. Previously, this worked as expected. Now after the upgrade, the Download Link sent in the email body only works if logged in to the FusionPBX web UI. If not logged in, I get the message "unable to download voicemail". I checked NGINX and PHP7.4 logs but didn't see any errors when the "unable to download voicemail" message is displayed. Server is running Ubuntu 20.04.
