Some of those works, thanks, I also see this one "addr" : "87.182.113.186:16281", but the wallet only syncs 1000 blocks more, each time I shut it down and reopen it. So I need to do that like 100-200 times more for full sync.

This is not normal. You should try to resync from scratch...
Backup your wallet and remove all data in the .Philosopherstone (Linux/Mac) or c:/user/yourname/AppData/Roaming/Philosopherstone (Windows)
You can use the bootstrap here to speed things up: we.tl/t-y0JVO8XRwg
Rename the file to bootstrap.dat and put it in the same folder as the Philosopherstone executable.
Launch the executable and let it sync, it will first process the bootstrap locally, then download the rest from peers.
Happy staking

Thanks, but I know all that, been doing this since 2011.
I left it overnite (sensation?) and it's synced now. Also have another node:
If it wont sync next time, I guess I have to do the hours long re-sync. We'll see.
