You do not have to actively do something to receive a transaction.
As TryNinja already said, check your transaction on a blockchain explorer.
If it shows as confirmed there (note: will show as unspent then -> unspent means you didn't spent them yet), you don't see it because you are not connected (indicated by the orange/red circle).
If you aren't using a VPN and are not from a country which heavily restricts the internet, the electrum server you are connected to is under attack or otherwise not accessible.
In this case, you might ask
mocacinno to whitelist your IP for his private electrum server.
Note: As long you have a backup of your seed (12 word mnemonic code), you will always have access to your BTC, regardless of the wallet used.
