I get a HTTP server error when I try and run multiple instances even off different directories. Can't run two instances currently.
Idiotically had config file still running qt as server. Currently am able to to run, bitcoind and qt after defaulting the qt config file. bitcoind from secondary drive seems to default still to the primary drive and qt was installed in secondary and operates there. I'll see if I can get BTCpay deployment moving now.
Lock this up please.
