I have tried the dumpwallet "filename" option, receiving the unencrypted file,
put it into electrum and it did not show my balance.
What did you import?
Note: Don't post your private keys here!Is it a private key starting with "5", "K" or "L", and 51 or 52 characters long?
Yes they start with a K or a L and also 51-52 long.
The wallet was encrypted but I did not have to type in my passphrase while executing dumpwallet. Maybe theres a clue?..
I imported the Keys directly into Electrum (standard wallet--> import private keys)

When I checked the backup of the wallet.dat file, I found out that I have somehow changed it in 2017, compromising the one of 2016.
An older wallet may or may not still contain funds, it depends on what else you did after making the backup.
I have made the backup in 2016 (of my encrypted wallet) and sent the funds to the receiving address.
Then, when I saw the funds are not arriving or at least not shown, I decided to click on the button: getting new "receiving address" or something similar.
After that I did manage to crash the Bitcoin Core wallet by ticking: running Port 8333 on every start of the Bitcoin Core wallet.
Well, as you might know from the post above, I did not manage to open my wallet from there, nor Port 8333 which left me a little confused and I decided to stop trying since , maybe you have guessed it, Im not the best with this kind of stuff.
From there on I was not able to access my wallet which could have helped to get at least my pub- and private key.
In 2017 I decided to make another backup, compromising the last one...
