Hello how are you?
the truth is that i install version 2.3 but it does not synchronize. and I do not know how to add the nodes and I do not know how to connect it. I admit, I am very inferior to you. Maybe I exaggerate, but if a friend wants to make a YouTube video showing step by step how to achieve it, I'll always be grateful for it. always. if I knew how to do it, I would help others. i need the wallet. :/
Just a guess, but I think you may have upgraded past the fork point, so instead of your client following the fork with other upgraded clients, you're stuck on a little stub with anyone else who didn't upgrade in time. The main chain is being extended but your client ignores the blocks because none link to the end of the chain you have.
I don't know if the bottlecaps client is able to "rewind" the blockchain to resync from the fork point. Based on my experience with other coin clients, I'd say not. That means you'll need to restore your blockchain database from an older backup (if you have it) or sync from scratch.
or not quite from scratch. in your AppData folder for caps delete (only) the blk0002.dat and blkindex.dat files.
the blk0001.dat you keep and it should take you up to mid July 2017.
then start the latest version of caps program with the -reindex command line option
