Did you need me to display the configuration of Electrum to use TOR 9150? If so let us know and someone or myself can easily point the direction to you!
@Coin-Keeper: Thanks a lot for the explaining response! So I've learned, that a blue connection button in Electrum network when using TOR is o.k. and the wallet is connected. Your comments in the remaining paragraph exactly describe the situation.
Concerning your last statement: Yes, it would be helpful for me to display the configuration of Electrum to use TOR 9150 - what I've used from the electrum documentation was “C:Program Files (x86)Electrumelectrum.exe” -s electrums3lojbuj.onion:50001:t -p socks5:localhost:9150. However only with partial (occasional) success - should I probably use/ try different electrum onion servers?
