doesn't work in isolated peertrees

[nocard-code]

It doesn't work into isolated peertrees (without public peers). Is there a issue known:

A) with tls://
B) without the tracker
C) any other

?

No, it is not designed that way. You need to be connected to the Yggdrasil network.

It's sensible on timing. MTU should be choosed wisely.

Now it works even with some bigger Files.

"Offline", that meens, without any Internetprovider.
