You may have that problem just cuz you`re using not secure resources. I can suggest you to use
bitcoin mixer for transfers and mixing various bitcoins. It`s secure and anonymous.
hmmm
bob123 was completely correct, NeuroticFish was mostly correct (unconfirmed transactions
should show up in electrum's history)... But Bitexpert11's sollution shows that he's not a Bit expert (pun intended).
I've never heared about the mixer that's being linked to (this doesn't mean anything, exept that it might not be a popular mixer), but more important: using a mixer has nothing to do with transactions not showing up in your wallet's history. As a matter of fact, using a mixer is just adding an extra variable in the mix. A mixer is usefull if you want to break the link between the senders and your wallet...
To repeat the previous posters:
- Verify if the transaction exist on a block explorer and is funding the address you entered while withdrawing
- Double check if the address is correct
- Change the electrum server by clicking the button in the right bottom corner
- Make sure you have an official electrum version (check the signature of ThomasV)
- Make sure you have the latest electrum version
- Make sure a local firewall isn't blocking you (either a firewall on your pc, or on your own network)
- Restart your wallet and reboot your pc
If nothing else works, but you are sure your address is correct, and a funding tx exists, you can always download a clean electrum copy on a new device that's on a different network, and restore your wallet from seed...
