There are TCP timeouts, but in situations where it fails instantly there would otherwise be no delay.
(E.g. firewall rejection, or when in flight mode.)

This change only makes it work when in offline/airplane mode.
When connected to a server it still crashes.
Likely due to a different part of the code.

Thanks to https://github.com/piplup55 for pointing out to me that this worked in old versions.
I then tested a few older builds and found out that it started to not work with version `v1.1.0`.
Using `git bisect` I was able to find out that commit 34691af introduced the issue.
