Hey! Does Opera have any additional privacy/VPN/shield/etc.-type settings that might be affecting how it connects to ChatGPT? Have you experimented with changing those settings, if so? It could also be a certain browser extension installed to Opera, possibly! Maybe trying in a private window of Opera, if you haven't already, could be a good test.

Hello! There is no specifical protection activated with the brower since I already protect me with another software. Therefore, I tryied with / without it and it stills not working. However, I will try the private window method ; then I'll come back to you. Thanks for helping btw.

Edit : The solution provided changes nothing. :/
