bitcoind – Error while syncing with the blockchain on my Raspberry Pi

So I already have the node set up on my raspberry pi. This night the transfer of the Blockchain from my laptop to the raspi’s hard disk finished. Now I am waiting for the blocks to match the headers

"blocks": 162064, "headers": 613982

The thing is that when I do bitcoin-cli getblockchaininfo to check if it is already complete, I get this error:

error: Could not connect to the server 127.0.0.1:8332
Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

I check if bitcoind is running with systemctl status bitcoind.service and this shows up:

● bitcoind.service - Bitcoin daemon

Loaded: loaded (/etc/systemd/system/bitcoind.service; enabled; vendor preset: enabled)

Active: activating (auto-restart) (Result: exit-code) since Wed 2020-01-22 11:59:12 CET; 15s ago

Process: 811 ExecStartPre=/bin/sh -c sleep 30 (code=exited, status=0/SUCCESS)

Process: 814 ExecStart=/usr/local/bin/bitcoind -daemon -conf=/home/bitcoin/.bitcoin/bitcoin.conf -pid=/home/bitcoin/.bitcoin/bitcoind.pid (code=exited, status=0/SUCCESS)

Main PID: 815 (code=exited, status=1/FAILURE)

So I try to restart the bitcoin daemon with sudo systemctl stop bitcoind and sudo systemctl start bitcoind. And when I check its status it shows the following (which looks good):

bitcoind.service - Bitcoin daemon

Loaded: loaded (/etc/systemd/system/bitcoind.service; enabled; vendor preset: enabled)

CGroup: /system.slice/bitcoind.service

└─865 /usr/local/bin/bitcoind -daemon -conf=/home/bitcoin/.bitcoin/bitcoin.conf -pid=/home/bitcoin/.bitcoin/bitcoind.pid

And when I do bitcoin-cli getblockchaininfo again, it doesn’t show me an error, but the number of blocks synchronized is lower than before. And a few minutes later, when I go check again it all repeats itself.

What am I supposed to do here?

Thanks
