Electrum wallet doesn't receive bitcoins

[Jane102]

Hello, my Electrum portable version of wallet stopped receiving bitcoins from 'get free bitcoins' sites. Now I have a standard version of Electrum recovered from seed on my computer, but it still doesn't receive any new bitcoins. I haven't lost my bitcoins but I've stopped receiving new ones.
Does anybody knows what happend with my electrum wallet? And what should I do to start receiving my free bitcoins again on the same wallet address?
