Failed to connect to server, please check your network connection(s) and try again

As the title says, when trying to connect to any online game on Project reality, that message comes up. I have no idea what is causing it, so I decided to come here and ask you guys because I'm struggling here. I have BF2 and PR updated too.

more often than not it's your firewall or antivirus blocking PRLauncher.exe and/or PRBF2.exe
make sure to make exceptions for those two executables.

Just checked my firewall, and as far as im aware, nothing is blocking anything that has to do with BF2, project reality or Punkbuster. I tried reinstalling punkbuster like a similar topic stated, but that didn't work. something important to note is that I sometimes struggle connecting to servers that my friends run (for example a multiplayer game on theHunter, where you connect to the hosts game) unless we use Hamachi. Not entirely sure why this is but maybe it could shed some light onto the situation?

would need info from you:
motherboard make and model
motherboard's ethernet model (or wifi module make and model)
wired or wireless internet?
firewall?
antivirus?
router?
modem?
ISP?

I need system specs from PRLauncher->Support->Copy to Clipboard Button->
paste everything here.

That's what I have from the support tab. Currently I am using windows firewall, and Bullguard antivirus.
I have a Netgear N150 wireless modem router DGN1000. using it with a wired connection. And my current ISP is TalkTalk, however we may be changing as soon as fiber optic cable hits our area (shitty countryside FTW)

Sorry for late reply, been busy. After turning off ipv6 it still isn't working. I also couldn't find parental filters, but as far as I am aware, there are none on my router at the moment.
