Grand Theft Auto Online issues

[Taalojarvi]

So i managed to snag a copy of Grand Theft Auto V during the Epic Games Sale and it has been an absolute nightmare to try and get online working on BSNL FTTH.
I'm using a VSOL HG323RGW ONT (Branded as Scopus) and running Firmware version 1.0.31-2004. I've configured Port forwarding as well as Set NAT Type to NAT 1.uPnP is also enabled and the ONT is showing up as Realtek IGD under network.
Any help into the matter will be highly appreciated.

Change dns or use VPN like cloudflare warp. Also check the firewall, it may be blocking something.

@Nitin I'm using Google DNS. If anything, IPv6 hasn't been enabled in my place (Thrissur city) yet

 

[GR2]

@Taalojarvi Check the firewall dude.

Can it be a port forwarding issue? I have GTA and I can play GTA Online flawlessly even though I am behind a CGNat.

@achaudhary997 upnp is already enabled so it's not port issue.

 

[Taalojarvi]

@achaudhary997 port forwarding is enabled. But I think I've done them incorrectly. Can anyone send me a screenshot for reference?

@Nitin Firewall on router is set to low mode. Windows Firewall is accepting incoming connections for Grand Theft Auto

 

[GR2]

@Taalojarvi Either use port-forwarding or upnp. Don't use both at the same time

 

[Taalojarvi]

@Nitin Port forwarding is setup and UPNP is enabled

 

[GR2]

@Taalojarvi don't use port forwarding. Leave it to upnp, it will open ports automatically.
