Can someone help me? I can't sync CroatCore app with the blockchain. When I open the app, it says it needs synchronize with the blockchain, but it can't connect to any of the nodes.
For some nodes it says:
2017-Nov-20 08:21:47.680901 DEBUG Selected peer: 12398755495621506974 195.214.150.84:46347 [white=1] last_seen: d39.h18.m18.s19

And for majority of nodes it says:

I don't have a wallet near me but look for a file called nodes or something and delete it, then start the wallet again. Fixes it for me.
I can't find the file named nodes. Could you please look it up? I can't access my wallet

Do you have some firewall or similar in this computer? can you check from other pc?
Try deleting the p2pstate.bin file.
Thank you so much! This helped and now my wallet is synchronizing

I have the same problem in macOS v10.13.3 and cannot find the file p2pstate.bin. Any suggestions?
