RESERVED WALLET Balance invalidated ):

This is not an issue related to Umbrel in specific. Is a bug in LND and was addressed here

Options that you have now are:

  • send a 100k sats to your node onchain address, in one UTXO
  • keep that UTXO untouched, as reserve for future opening channels
  • add this line in your lnd.conf at the end of the file
  • restart the node
  • try again opening the channel. If still can’t open, try sending more UTXOs to your node, but at that level is not realistic anyway and you should wait fro the new version of LND v 0.14

THIS IS BUG IN LND! And a much better approach is to not open channels until v 0.14 with a fix will be released.
