hmm now it doesn't occur anymore. don't know why. update maybe? in that case, thanks opera!

So is there a solution to anyone who still might have this problem?

Hey, I just started using Opera after being fed up with Chrome's resource hog, and I like it a lot so far! One issue I've had, though, is that all twitch streams appear offline until I disable Opera's feature that blocks "insecure content." The player seems to work fine (I can regulate volume, open the settings overlay, etc.) and so does the chat, it's just the stream that appears offline.

Now I'm thankful for you looking after us, but it would be nice if we could have an exceptions list for the content blocker, just like the built-in ad blocker has. I don't know if Opera blocks twitch streams intentionally, but twitch is one of my main sources for entertainment, so it would be nice if I didn't have to manually disable the blocker every time I open a stream. I might consider trying out other browsers if this problem persists. Thanks in advance for any responses!
