I am trying to setup a link on my website to auto open Steam and load a game at a specific server. It was working at one point, but now I get this. You can see in the address bar there is the "denied:" added to the front. If I remove thatn and paste the rest to the browser it does what it should, however, for some reason this is getting added and I'm not sure what more I can do resolve this issue. I've been researching it all day so hopefully someone has a solution.

I'm using the latest Opera version. I did not find any way to add protocols in Opera. I can only delete ones and the steam:// protocol is not shown in the list. I've also checked my Windows 10 application associations and protocols and did not find anything related to Steam in there.

Any help would be much appreciated.
