Stupid question: Why am I unable to get mempool up and running locally?

[torstenbm]

Hi!

Sorry in advance for seeking help debugging, but I have been unable to get mempool up and running locally. I.e. I technically get it up and running, but the UI only ever gets this far and I am unable to figure out why.

I've tried spinning it up both with docker compose and with npm, but with the same result. Looking at the logs it seems to be able to connect to my electrum server just fine

> mempool-backend@2.6.0-dev start
> node --max-old-space-size=2048 dist/index.js

I don't really see anything in the logs about it connecting to bitcoin core, but I've given it all the correct info and when running

curl --user rpcusername:rpcpassword --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockchaininfo", "params": [] }' -H 'content-type: text/plain;' http://10.0.0.41:8332/

I am getting the expected response, so I see no reason why mempool would be unable to connect to it.

Any help on how to proceed in order to figure out why I'm not getting it to run locally would be much appreciated! Thank you very much and keep up the good work!
