Not able to establish Successful peer-peer connection over BSNL network on parsec

[SS2599]

Hi Guys,
so I'm currently working from home and I was using parsec but now due to service issue from ISP I switched to BSNL fiber and while using this network now I'm not able to establish connection on my remote computer it shows -6023 error but at the same time I'm able to make connection using my phone hotspot. when I try to connect another system on same network on BSNL wifi it works but it dosent work on remote network. I guess it is happening because for carrier grad NAT issue. i'm very clueless how resolve this issue now. it will be great help if this issue resolves

I have used parsec with BSNL FTTH and it has worked fine, around 12-13 ms ping bsnl to bsnl and 40-50 over other connections. How have you setup port forwarding? And what network configuration do you have at the remote and host machine?

Does it work with Tailscale installed on both devices?
