I have been looking around quite a bit about ways to solve this error and none of them have worked. To give some context, I am running a full node on a raspberry pi and everything is working just fine from the command line. I am able to write bitcoin-cli commands and it gives me the results just fine. When I write bitcoind in the command line to show if everything is working, it says that it is unable to an http server (the error in the title). Does anyone know how to fix this?
My bitcoin.conf file looks like this:
server=1
rpcuser=<username>
rpcpassword=<password>
txindex=1
