Wallet not connected

[muchomurka23]

I updated my Electrum wallet to version 3.0.3 on Tails and recovered my old wallet but i couldnt connect and synchronize. I tried to change servers manually but there is always red dot. Any ideas how to fix it?
Why i updated electrum?  My friend sent me some BTC but payment was pending for 5 days so i thought that problem is in my expired version of wallet.

What version of Windows you use(if you use Windows),because Windows 7&8 have problems with Electrum version 3.If you use this version of Windows then is better to get previous version of Electrum 2.9.3.

If you using Windows 10 or Linux try to delete blockchain_headers file which is located in /C: Users/Home/AppData/Electrum.After you delete that file Electrum will try to sync again,you should wait few minutes for full sync.

I have Linux Tails. I cant find blockchain_headers.

I think Tails uses Tor by default doesn't it? You might need to configure Electrum to use Tor.

I'm not sure how up to date these instructions are: http://docs.electrum.org/en/latest/tor.html ... but maybe it'll get you going?

The problem with Electrum, version 2.5.2 portable. Essence: included after a couple of weeks, and writes "Synchronization" .. and already 2 days, changed the download server. It does not help, even on the contrary - the red circle glows. In what there can be a problem and how it to correct ??
p.s have Win 7 and recently updated all the drivers, after that Electrum stopped switching on
