Disclaimer: I've attempted to read (and comply) with the forum rules, so if I have posted in error -- please look kindly on me. I am new.
Recently I tried launching some games (the need internet access) and found that no matter my configuration I was unable to get them to connect!
I'm on Fedora, but have observed this behaviour on other distros I have running. I tried googling a lot of different solutions and never had any success. So I'd like to leave this simple bit of advice for anyone else going down the same rabbit hole.
My issues were solved by running the program with sudo.
i.e. $> sudo wine64 /path/to/app.exe
Word of warning to new users -- malware in a windows application running with root privileges is bad thing -- so please be certain you trust the software you're going to run like this.
To the mods:
Again, very sorry if I've made some mistake but I really genuinely tried to just reply to the relevant thread but it was autolocked.
