Sparrow cannot access Bitcoin Core started by systemd

[castleRockHill]

I run Sparrow on one computer and Bitcoin Core on another.
If I start BC from the command line (bitcoind -daemon), BC runs fine and Sparrow can access BC.
If I start BC from systemd (bitcoind -daemon in a unit file), BC runs fine but Sparrow cannot access BC.
Same conf file in both instances.
Any idea why this might be?
Thank you.

Does your Bitcoin Core from systemd run as the same user as when you start Bitcoin Core from the command line?

Have you checked that both instances of Bitcoin Core actually read the same settings from bitcoin.conf file?

Have you tried connecting with bitcoin-cli or other methods (like with curl) from the computer where Sparrow runs to your Bitcoin Core on the other computer?

bitcoin-cli help command gives you examples how to talk to Bitcoin Core via curl.

Would you post the content of your bitcoin.conf, settings.json and your unit file? (Make sure to redact anything that could be detrimental to your privacy. Redact RPC access credentials, if you've set them up.)

Put file content properly in [code]...[/code] tag blocks.

Without additional ramification, i would suggest debug.log to see whether same configuration/argument loaded by Bitcoin Core. On my node, i see something like this.

Code:

[datetime] Config file args: ...
[datetime] Config file args: ...
[datetime] Setting file args: ...
[datetime] Setting file args: ...
[datetime] Command-line file args: ...
