BTC: NBXplorer error `Response status code does not indicate success: 401 (Unauthorized).`

See original GitHub issue

Hello, I’m configuring a fresh NBXplorer+BTCPayServer but I’m stuck on this error from BTCPayserver

BTC: NBXplorer error Response status code does not indicate success: 401 (Unauthorized). It seems very strange to me since at startup I have:

info: Configuration:  Data Directory: /home/archbox/.btcpayserver/Main
info: Configuration:  Configuration File: /home/archbox/.btcpayserver/Main/settings.config

NBXplorer is correctly listening on port 24444 and I don’t have errors in NBXplorer log:

Any ideas or suggestions about my configuration? Thanks in advice.
