@Bellsmm it still doesn't work. I wouldn't waste your time trying until Opera devs confirm the fix. It looks to be a protocol error, so something isn't communicating within internal Opera systems, rather than a failure to communicate with GPT itself. As far as I'm aware, there's nothing you can do to fix this on your local machine unfortunately.

Agreed - same issue here.

Hoping the Opera dev team fixes this soon.

It was working fine previously but it stopped connecting as of yesterday - still no luck. I think it may be a bug on Opera's end.
