RPC port 8332 not accessible after reboot

[nemomaximus]

I have compiled and installed Bitcoin Core for the first time on Debian 11. Everything is up and running except that RPC port 8332 is not accessible after a reboot.

I get the following error running bitcoin-cli getblockcount:

error: timeout on transient error: Could not connect to the server 127.0.0.1:8332

If I then run systemctl restart bitcoind then everything works fine.

systemctl status bitcoind shows that it is up and running just fine after a reboot.

Look at this after the reboot:

Code:

netstat -nap | grep bitcoin | grep LISTEN

tcp 0 0 0.0.0.0:8333 0.0.0.0:* LISTEN 456/bitcoind
tcp 0 0 127.0.0.1:8334 0.0.0.0:* LISTEN 456/bitcoind
tcp6 0 0 ::1:8332 :::* LISTEN 456/bitcoind
tcp6 0 0 :::8333 :::* LISTEN 456/bitcoind

And then after systemctl restart bitcoind:

Code:

tcp 0 0 127.0.0.1:8332 0.0.0.0:* LISTEN 532/bitcoind
tcp 0 0 0.0.0.0:8333 0.0.0.0:* LISTEN 532/bitcoind
tcp 0 0 127.0.0.1:8334 0.0.0.0:* LISTEN 532/bitcoind
tcp6 0 0 ::1:8332 :::* LISTEN 532/bitcoind
tcp6 0 0 :::8333 :::* LISTEN 532/bitcoind

For some reason the 8332 port is not opened on reboot...

Any idea what will solve the problem?

Any idea what will solve the problem?

Can you share your bitcoind unit file (bitcoind.service file)? I only could think it's caused when bitcoind started. But if you don't mind ugly workaround, edit your crontab to restart the service shortly after boot.

Code:

@reboot sleep 30 && systemctl restart bitcoind

That's not very clean though. I would first ask OP to send their systemd service file and to have a look at the debug.log of Bitcoin Core; usually there's something useful in there.

I do suspect that it's something like missing a After=network.target or something like this.
For reference, I use:

Code:

[Unit]
Description=Bitcoin daemon
After=network.target

[Service]
ExecStart=/usr/local/bin/bitcoind -daemon -conf=/home/bitcoin/.bitcoin/bitcoin.conf

# Make sure the config directory is readable by the service user
PermissionsStartOnly=true

# Process management

I basically use the the "/bitcoin/core/bitcoin/contrib/init/bitcoind.service" which I just slightly edit...

I was able to solve the problem by adding the following to the bitcoin.conf file:

Code:

rpcbind=0.0.0.0
rpcport=8332
rpcallowip=192.168.230.0/255.255.255.0

Yes, correct
