Sync works very bad since core v.3., connections poor
I think your issue might be related to port forwarding. Check out the wiki https://wiki.qortal.org/doku.php?id=port_forwardingIf that doesn't work out, ask in the Discord https://discord.gg/MhxRpGyaDD there are tons of smart folks there.
Everything worked fine until v.3. With v.3 and QDN sync start to work terrible.

I was in Qortal Discord...But later i left...Because of Qortal Rose!!!
Her pictures are infuriating and annoying...
She's ready to put a Q and QORTAL in every picture with damn Paint...
Fuck, teach her Photoshop to make beautiful pictures!!!
