I have a Windows Server that acts as a full node where other clients from PC connects and synchronize with it, all is ok, then I decided to add another hosted vps based on ubuntu 18.04, it doesn't synchronize even it seems number of blocks, I opened the tcp port with ufw but I don't know why it's not syncing:
