I’ve got exactly the same error. I’m using Win7x64 - started FiveM- ignored the stupid “go buy win 10 message”(really wtf guys), went to settings, clicked “link” - some browser window appeared, clicked “authorize” - seeing shortly in the left corner of the browser “sending request to forum.fivem.net” and thats it, nothings happens, i can click the authorize thousand times and nothings happens, trying different browsers did not work either, trying the suggested solution here: Need Help with Linking FiveM Account didnt work either. according to this fiveM should open if i click on link - but instead - nothing happens. Help please, is there any workaround to manually link the account?
