is the node running on neutrino or as a full node mode?

[mayankchhabra]

bitcoind backend, his node is fully synched.

[nolim1t]

I can reproduce this on my testnet node too

[nolim1t]

However testnet.getumbrel.com is fine

[nolim1t]

a few other users are reportedly getting this too

[nolim1t]

This is a dashboard issue with it calculating rates..

Open channels is fine without the dashboard

[nolim1t]

The slider also doesn't work too

[mayankchhabra]

Ah, shit. Do you get it on both your testnet and mainnet nodes?

[nolim1t]

I've seen it on mainnet.. .. users are reporting it on both

[nolim1t]

I can reproduce this myself on testnet.

My versions:

• getumbrel/middleware:v0.1.3
• getumbrel/manager:v0.2.0
• getumbrel/dashboard:v0.3.1
• lncm/bitcoind:v0.20.1 (not relevant to this)
• lncm/lnd:v0.10.1-experimental (not relevant to this)

request that returns:

curl 'http://blahblahblah.onion/api/v1/lnd/channel/estimateFee?confTarget=0&amt=100000&sweep=false' -H 'Referer: http://blahblahblah.onion/lightning' -H 'Authorization: JWT blahblah' -H 'Connection: keep-alive'

getmempoolinfo from bitcoind returns on testnet (practically empty)

{
  "loaded": true,
  "size": 0,
  "bytes": 0,
  "usage": 0,
  "maxmempool": 512000000,
  "mempoolminfee": 0.00001000,
  "minrelaytxfee": 0.00001000
}

Ah, I see. Can you try setting minrelaytxfee=0.00000001 in bitcoin.conf, then restart both bitcoin and lnd, and see if you're able to open channels through the UI?

[nolim1t]

cool that worked.. no need to touch lnd

[nolim1t]

moved back to umbrel project as its just a config
