Why can't I import the private key into Bitcoin?

Question

bitcoin

Hello. I use an Electrum wallet. I want to import my private keys (private keys) into any other client. In electrum performed the export of keys. Then, I try to import them to wallets in btc.com and blockchain.info but the services say that this key is wrong. What am I doing wrong? I get the key in Electrum like this:
1st step: prntscr.com/iaim1j
2nd step: prntscr.com/iaimwq
What am I doing wrong?

Answer 1

1. check the version of Electrum (should be 3.0.6)
2. remember that two-factor authentication was chosen when creating the wallet - as a result, output management requires a multi-signature.
This is hinted at by the number 3 at the beginning of the address and Redeem Script when trying to export.
3. swear, write on the wall "never choose to use protection technology, the principles of which you have not understood the minimum!" =]
4. if you want to use one address in several wallets, send money from multisig chamber to a "simple" address (generated either in the same blockchain.info, or in Core, or in any other generator)
Here is a private one from it the key can be imported even into Electrum, even where.
Yes!
BTC.com does not import keys from empty addresses and may give an error when importing some keys (with an address balance less than the fee required to spend it, as well as for BCH used in the network)
I'm talking about regular, not multi-sig addresses.

Answer 2

Try importing to Blockchain.info. Everything works there without problems.

Answer 3

the formats are different, of course
look for where what base
