Testnet3 app will not sync to peers I was just trying to connect testnet3 to my own testnet node through the &quot;trusted peer&quot; and &quot;skip regular peers&quot; settings, but it seems that in this way it cannot connect to a trusted peer which runs 0.21.0.
I tested several 0.21.0 nodes and it does not connect to any of them. However, it does connect to a trusted peer which is 0.17.0, for example. Also, with default settings (no trusted node) it displays some 0.21.0 nodes in the peers list, not sure why.
Did anyone notice this and managed to find a workaround? Thank you.
I was able to connect one of my node with other (both v0.21.0)

I copied the IP address from local address returned in getnetworkinfo
Used it in bitcoin.conf of other node in below format:
testnet=1
test.addnode=IP
