Issues with IKEv2 IPSec VPN on Rogers LTE/3G

[JP1204]

This is on an iPhone 7 connected to Rogers LTE or 3G wireless networks. 

I'm having an issue when using IKEv2 IPSec on NordVPN. The VPN connection gets established properly and connections through the VPN appear to work, speedtest works, many sites come up fine, etc. But some websites just never connect (e.g. https://us.opinio.net) through the VPN, others like https://www.reddit.com work 50% of the time. 

Using OpenVPN UDP port 1194 on the same NordVPN server instead of IPSec, there is no issue at all, so it's not a matter of the NordVPN server being blocked by the sites, or itself blocking requests. 

To rule out my phone or NordVPN, I switched the SIM card to TELUS LTE and both VPN modes work just fine, IPSec and OpenVPN. There is also no issues over WiFi.

There really seems to be an issue with Rogers and the connection through IPSec.

Do you guys have an idea what's going on? 

I found a thread where RogersDave suggest switching PDP Type to IPv4 instead of IPv6, but I see no options to do that on an iPhone 7. 

Thank you!

VPN (L2TP) not working over LTE?

Is anyone else having trouble connecting to VPN over LTE?

Has a issue a few days ago, then suddenly started working again. Today not working at all. I have been checking my routers and network etc. without success.

I am able to connect to my VPN server from Bell LTE and from WIFI networks and even internally within the same network but nothing over Rogers LTE?

I can see the packets hitting the router from Rogers LTE but the connection just won't establish.

Has something changed?

Anyone else having issues?
