Electrum not sync

Hi, Electrum wallet not sync. Version 3.3.4. Pls, tell me what to do?

What is your OS?
Have you tried charging servers manually? (on Tools -> Network)

Your OS?
Did you download Electrum from https://electrum.org/#download ?

Yes.

Can you check if there is an expetion on your firewall (Windows 7) for Electrum?

Go to %appdata%/Electrum and delete the blockchain_headers file. Then, rerun Electrum and wait a few minutes for it to synchronize. See if that fixes it.

Also, is your Windows 7 up to date? Can you check for new updates on Windows Update?

I think i need VPN, or proxy. But how to use it?

iplayboy, did you just click on server or use right click and click on "use as server"? Electrum will not connect to new server if you not uncheck “select server automatically”, and use option which I mentioned.

Problems with sync can also be because your antivirus / firewall is blocking Electrum, so check that if there is no luck with server changing. Did you use Electrum before 3.3.4, maybe some files get corrupted during update?

Please also show us the "Proxy" tab

Lucius suggested that you un-check the Select server automatically option but from your screenshot you didn't do that. Un-check the option and select a server manually from the list.

Yes and to select a server manually you have to right click on a server and choose 'use server'. Left clicking will not do.

Also do post a screenshot of the proxy tab if switching servers doesn't work.

I used right click on a server and choose 'use server', but nothing too.

And why is the "Select server automatically" box still checked?

You seem to be using the same server as in the previous screenshot. I just tried it and my Electrum doesn't synchronize with it (btc.smsys.me with port 995).

Uncheck "Select server automatically", right-click a different server, "Use Server", click "Close"; That's it. Keep the checkbox unchecked.

Try selecting the server electrumx.ddns.net - I just tried and it synchronizes (as of now).

I tried all the servers manually - nothing.

Can someone tell me a working Proxy?

They are talking about this (because all of your screenshots showed that it is still checked):

The proxy tab isn't enabled thus it's not the main issue at least.
Are you sure that it's unchecked before selecting a server, Yes?
Maybe it's a problem with your internet connection, firewall or network-related issues; is this connection issue only happens with Electrum?
