WireGuard fails to connect over GPRS

[jichef]

Hi! First of all thank you for your code. It's been easy to understand with your example. Anyway, it works when I am connected to a wifi but it isn't when I use a GSM connection over my board (Lily T-SIM7000G). I have tried your code in the same device, with wifi and GSM and, always fails with the GSM.

Can you shed some light?

I can confirm this.

But after some retries it was able to connect properly via a wifi hotspot on my android phone or my local internet connection wifi.

After changing the connection informations and uploading the code to the ESP32 the connection will not working (connection to WIFI yes, to WG no)
after making no changes and reuploading the ESP restarts and than WG starts working again.

This happens when I switch to LTE or to Local Wifi...

Another reproduction was not possible for my.

Hi! In other GitHub post someone (ciniml/WireGuard-ESP32-Arduino#34 ) said that the issue may be with how TinyGPSPlus provides the interface and I found this, but couldn’t made any advance trombik/esp_wireguard#39 (comment)
