p2p & ZeroTier - can't see other players

[AwouldLikeM]

We are using ZeroTier custom network along with p2p option (in desire for a better synchronization). Although we can successfuly connect to the server (running on my end), we do not see each other. This only happens with the p2p turned on.
Server config:

...
	<UseP2P>true</UseP2P>
	<UseZeroTier>true</UseZeroTier>
	<UseVoice>false</UseVoice>
	<ZeroTierNetworkID>*redacted*</ZeroTierNetworkID>
...

So what might be the issue here? Port is forwarded on the router and allowed on my PC.

It may be due to the updated Lidgren.Network in the latest release (actually it's the same library, only changed to a release build which has better performance than the debug build used previously).

Please try with this version, I reverted to the debug build
