I need some help installing a local instance of mempool.space, hoping some of you with experience can chime in.
I've installed all the dependencies using
apt, so they should all be stable LTS versions. I also installed npm.
I am trying to run this on separate hardware than my bitcoind and electrumx services. On the mempool machine I set up the config file with the node server's local IP, and an rpc password generated using rpcauth.py. On the node server I added the user authorization to the bitcoin.conf file, opened the applicable ports in ufw, and set port routing in my router. I double checked all that over and over, so I'm sure that's not presenting any issues.
I installed nodejs and mariadb only on the machine that'll be running mempool, not on the machine running bitcoind/electrumx.
Here's the error I get when trying to run the backend:
direwolf@mempoolserver:/usr/local/bin/mempool/backend$ sudo npm run start
> mempool-backend@2.2.2 start /usr/local/bin/mempool/backend
> node --max-old-space-size=2048 dist/index.js
/usr/local/bin/mempool/backend/dist/index.js:24
wss;

Here's my mempool-config.json file. I only changed the rpc password in two places, and the IP address in thee places (as shown below.)
