Hello again, my problem's root was using Scaleway instances as server nodes . Scaleway developer instances do not know about their Public IPs , thus they were sending local addresses in the addr and sockAddr arrays. When I set up my server nodes on digital ocean instances , everything was solved.
example from scaleway , which is not working: addrs=ArrayList [0:0:0:0:0:0:0:1%lo, 10.18.122.155, 127.0.0.1, 2001:bc8:1824:154d:0:0:0:1%ens2], sockAddrs=HashSet [2001:bc8:1824:154d:0:0:0:1%ens2:47500, /10.18.122.155:47500, /0:0:0:0:0:0:0:1%lo:47500, /127.0.0.1:47500] example digital ocean node's arrays: addrs=ArrayList [0:0:0:0:0:0:0:1%lo, 10.15.0.5, 127.0.0.1, 188.166.219. <http://188.166.219.180/>XXX], sockAddrs=HashSet [/0:0:0:0:0:0:0:1%lo:47500, /127.0.0.1:47500, /10.15.0.5:47500, / 188.166.219.XXX:47500 <http://188.166.219.180:47500/>] How can we set scaleway server and client nodes' configurations , so that they send correct public IPs for tcp communication ?
