Hey.

Recently I have trouble opening a channel in Lightning network Swaps. I used Thunder or RTL to open it.

The reason I failed is simple. I can see in apps a script ’ Received Funding Error From 0205198c099c45acedf988445f71da087ca39cd80847e53a7819e8f4e45768d7d3: Chan\_id=449936dc01f79eb499150ece7a8a3868036f7376a852d0478b2a685d059ec19c, Err=you Gave Bad Parameters: Feerate\_per\_kw 2500 Below Minimum 4971. '.

I found that it is related to anchors commit fee rate. It is now set at 10 sats/vb currently (2500sat/kw), and the minimum required to get above the error, nearly 20sats/vb (4971sats/kw).

I am not good at coding. I want to set the fee using RTL or Thunder without using codes.

So how can I set the fee rate for my channel? or Any other idea?

Thx.

Umbrel Lightning Node App  
 → Advanced Setting  
 → Channels, Maximum Anchor Channel Commit Fee Rate 10 -\>20.  
 → SAVE AND RESTART NODE

Try to open the channel.

I don’t know about Core-lightning.
