I tried the following:

From the logs i understood something i have issue on routing tables.

Before connect to my VPN

maa1apnb663183@maa1apnb663183:/var/log$ sudo route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.1 0.0.0.0 UG 600 0 0 wlp2s0
143.116.250.163 192.168.0.1 255.255.255.255 UGH 1 0 0 wlp2s0

192.168.0.0 0.0.0.0 255.255.255.0 U 600 0 0 wlp2s0

After connected to my VPN

maa1apnb663183@maa1apnb663183:/var/log$ sudo route -n

I have tried this step on internet by adding duplicate entries on(Network connections -> your VPN connection -> IPv4 settings -> Routes -> Add ...) and checked "Ignore automatically obtained routes" checkbox. - restarted VPN connection

But no luck still my issue persist .

One important note: When am connecting to Airtel broadband I have no issue with my VPN one week before I switched my Home network to ACT afterwards am facing this issue also I dont find any issues when tried in my mobile network by tethering.

I have seen on internet many of them facing similar kind of issue but mine i suspect due to ISP.

Any suggestions guys ?
