we have upgraded from R80.30 to R81 and we discovered that HTTPS Inspection has some problems there.
for example on youtube.com some video images are unable to load, these images are loaded from ytimg.com. after bypassing ytimg.com issue is resolved.
same repeats not only for youtube.com but for several websites, for example: workspace.com, admin.exchange.microsoft.com, ui.com, for some facebook.com, microsoft.com pages and many more.
In overall it looks like some content can't be inspected and is stuck somewhere.
I can't just bypass everything :))) maybe there is some fix or any experience about it? you can see my settings in attachments.
