Avast Pro on Mac blocking music services

I am running the latest Premium Security version on an iMac desktop. All MacOS and other SW is fully up to date.

Recently, I am seeing a few services blocked by the AV tool. I can easily verify this by turning off Web Shields, in which case these services work. And these issues also do not show up on other PCs/devices that I use. Two services in question are 1) LiveXLive (Slacker Radio) playing through the Sonos system, and 2) dbPoweramp CD ripping software, which accesses Accuraterip and a few other services.

I am sure these services must be accessed via APIs, in which case there should be one or more URL exceptions I can add in the AV tool to allow them. I tried the obvious livexlive.com and accuraterip.com, to no avail. Is there a way that I can discover the URLs that I should add as exceptions - some kind of log that I can browse to view what is being blocked?

Thank you.

Usually there is a notification pop-up of what was blocked that should contain the blocked file or URL. Open Avast and click notifications at the top and you should see the current/recent notifications

I just wanted to follow up and say that these sites are no longer having issues while Avast is running. I did not make any changes, so perhaps a new update resolved the issue. Thanks!
