No IPv4 connectivity on cellular network
- /e/ version: 2020051454221
- Device model: Galaxy S8, SM-G950F
- When it started to occur: ?
- Reproducible with the last /e/ version: yes
- Reproducible with LineageOS: ?
Summary
I'm not sure if this is an issue with /e/ OS, the device, or the mobile network. If the device is only connected to the cellular network (Deutsche Telekom), the device gets an IPv4 and an IPv6 address but is only able to communicate via IPv6. Servers without IPv6 address are not reachable. I cannot tell when this started because I used this device (got it just some days ago) because of the Corona restrictions only at home with WiFi until yesterday. However, another phone on the same cellular network works fine.
