Firewall

#Client

If you use a launcher like this one, all internet access for GTA5.exe is blocked by it (Which is a good thing cause you don't want to give R* any chance to ban you for having fun). That also means you cannot connect to the GTACoop master server and therefor won't be able to see servers ingame.

In result, if you want to allow GTA5.exe to have internet access to the master server and Coop servers you'll need to add 2 new rules to your firewall.

It's up to you how you'll add them.

###Adding rules manually I have simple exported the 2 rules as csv to you so you just need to create new rules and take the values from the text below.

Name,Group,Profile,Enabled,Action,Override,Program,Local Address,Remote Address,Protocol,Local Port,Remote Port,Authorized Computers,Authorized Local Principals,Local User Owner,Application Package,
GTA Allow Coop Master Server,,All,Yes,Allow,No,S:\Grand Theft Auto\GTA V\GTA5.exe,Any,46.101.1.92,UDP,Any,80,Any,Any,Any,Any,
GTA Allow Co-Op Servers,,All,Yes,Allow,No,S:\Grand Theft Auto\GTA V\GTA5.exe,Any,Any,UDP,Any,4499,Any,Any,Any,Any,

###Adding rules through Windows Firewall Control
