@nvmjustagirl As I've pointed out initially, the target-page does not always fail with the VPN on. It's a function of the response time of the server being accessed and various network issues. My point was that I have used several browsers to access the target-page (IE, Edge, Chrome), they have never failed to return the target-page. Only Opera with VPN-on has timed-out, returning the response saying "no data was received". I recognize that the VPN itself can exacerbate the issue, and I've demonstrated this by trying to access the target-page with VPN-on, and repeatedly received the "no data" response, I then turned the VPN-off and was able to receive the page the first time without issue. This clearly suggests that the VPN is exacerbating the problem; but can easily be addressed by increasing Opera's timeout delay when the VPN is active.
It is also understood that currently only Opera offers a VPN, it is also generally recognized that the VPN can reduce the response time. It seems reasonable that if the Opera browser has a fixed timeout (with or without VPN), certain websites combined with the VPN could exceed the timeout.
Have a nice day
