Keeps trying ipv6 on a non-ipv6 network

[androidacy-user]

Hello!

IPv6 is blocked on my current network, but Matomo keeps trying to send data over IPv6 with the following error:

Transmission failed unexpectedly.

Nothing else in the app is having network issues. After three tries, it seems to transmit successfully over IPv4.
