This is my first post, I'm sorry if it's in the wrong place.
Let's preface this with having ports forwarded and an edited options.ini.
As the title suggests. I am unable to connect to another player, possibly certain players (at least 10), whilst I am hosting. But if they host I connect to them straight away. This is in a 1 vs 1 scenario. More players are a no go in general.
I connect to other peoples hosts whilst having my windows firewall (I only have the standard firewall) on. I turn it off when I host to no avail.
I am not the most computer savvy but hopefully I haven't missed something totally obvious.
Any help will be greatly appreciated.
