First the slashes should be like that ://.
And there is no port? If there is you have to include it in url.... If it still not work give me a debug log so to see.
P.S. Do you have google dns 8.8.8.8 blocked? If so you can adjust the setting to not do that check. Also your setup is for xtreme codes. Is that correct?
I’ll check it later today. I might have made a stupid typo.
