So I should change the servers manually in Electrum and just look where the unconfirmed transaction not appears? Is this right?
I'm not sure as to how Electrum treats unconfirmed transactions when the server is changed. You can try.
Is there a option to abbort the transaction?
Otherwise, I have a decent method that you can try.
1. Disconnect Electrum from internet.
2. Go to %appdata%/Electrum if you are using Windows.
3. Go to wallets and copy out your wallet file to a safe place.
-Warning. This can be dangerous if you don't know what you are doing or do not have a backup-
4. Open your wallet file in the %appdata%/Electrum/Wallets with a text editor.
5. Find f890011a4179e093f92a22be1e7f2c868af9929f1f2c173616a5968be934b704 with your text editor.
6. Search and delete it without modifying the [ and ]. So, for instance, I want to delete aac49, delete the [ and the ] part.

It will become

]
7. Do this such that you are not ruining the syntax.
