Seed and xPUB Key showed the same.
After I changed the gap limit both showed the true value.

Donated on the public wallet of both of you.

It works!
Thanks to @nc50lc and @BitMaxz.

The problem was the gap limit.
I think that because of some errors many unused addresses were created and therefore the addresses with the btcs were not listed.

Now it works with electrum.

Thank you very much. 0.5 BTC was the amount.

You both can write me an private message. I will donate 100€ in btc for each of you.

Greetings

Yeah, I am switching the payment gateway. In the future I will use an own btc gateway to receive the payments.

Yes, but the problem is that I received several payments and they are not listed.
I also tried to use electrum with the seed of my blockchain wallet. The payments are also not listed and I dont have access to them.

Therefore the received payments must be linked to another wallet although I got them with the xPUB Key from my blockchain wallet.

I also tested it several times with own payments. Same problem.

Hello,

I am using blockchain.com Wallet with their API and the xPUB Key to create addresses automatically.

The problem now is that since the first february all addressess that I create with my xPUB Key are not linked with my wallet.

If I use this address for receiving payments I am not receiving these in my wallet and dont have access to them.

I am using a bitcoin wallet.

I opened an support case on 02.06.2020 with no answer yet.

Do anyone also had or have this problem and can tell if blockchain.com replaced the missing balance?

The missing value is between 3000€ - 5000€. I haven't fully recalculated it yet.

Greetings.
