TLS Error: client->client or server->server connection attempted from

[davidvp]

Hi guys,
I was trying to config my openvpn during weeks and it is almost impossible.
My current topology:
- I have my IPS Router exposing a port
- After this, I have an Ubiquity EdgeRouter with OpenVPN

Scenaries:
- Mac connect to WIFI and Openvpn client pointing to EdgeRouter port👌
- Mac connect to 5G and Openvpn client pointing to ISP port👌 (it was difficult but it is working)
- Iphone connect to WIFI and Openvpn client pointing to EdgeRouter port 👌
- Iphone connect to 5G and Openvpn client pointing to ISP port🙅 My feeling is IOS is not able to put the info coming from push-route

I would like to solve my last case. I am using the same ovpn file like Mac. The log in the server are showing this lines:
