Hey again,  
I have installed BTCPay server on my Umbrel pi node and I am getting this message and error in a BTCPay server popup, even though my bitcoin node is 100% synchronized:

* * *

#### Your nodes are synching…

Your node is synching the entire blockchain and validating the consensus rules…

#### BTC

- The node is offline
- Last error: Connection refused (10.21.21.20:32838)

* * *

Any idea why I am still getting this message? I installed BTCPay server last week, and have had the message since. I installed BTCPay server after I had already synchronized the bitcoin blockchain, so it was synced from the start.

Where can I go online to get some support for this? I want to chat or use a forum or something where you get feedback.

Is it possible for someone to explain what the number in this error is?

Last error: Connection refused (10.21.21.20:32838)

Where is BTCPay getting this number?  
Is it an IP address and port?  
How can I edit this?  
Is this something to do with my Bitcoin node?

I have removed BTCPay from the node, rebooted the node, and added BTCPay again, and I still have the exact same error.

In my Umbrel logs I see this for BTCPay server:

btcpay-server

web\_1 | fail: PayServer: BTC: NBXplorer error `Connection refused (10.21.21.20:32838)`

This line is repeated over and over.

Hi, have you figured this out? I’ve just started getting this " Your nodes are synching … " and the error as well, although it is slightly different

`> Last error: Connection refused (btcpay-server_nbxplorer_1:32838)`

I assume the difference will be due to the newer version of Umbrel I am running now (May 2023).

Thanks for anyone’s help!
