pay: MPP fails over a single channel
Issue and Steps to Reproduce
Experiencing a similar issue to #5250 trying to pay simple $5 invoice to a BTCPayServer of Lunanode.
My CLN node has a single channel to a routing node currently still the pay plugin wants to send with MPP all the time.
There is no other way, but to put disable-mpp
in the config.
It seems this will need to be done for all nodes with only one channel otherwise CLN cannot pay anything.
The connected routing node can pay the invoice every time and also CLN can if disable-mpp
is set.

Trying an other time after a successful payment without MPP, it went through from the same node with MPP in 3 parts as well. MIght have really just been a pathfinding issue.
lightning-cli pay REDACTED

}
Still an option in the command line to control the number and size of parts would be useful to not need a full restart to changing this setting for a payment. Zeus already has this (but not sure how it is achieved):
Just like to say here, that i have this problem too. The max i can pay through my own channel directly to my peer is
"spendable_msat": "4294967295msat"
It takes me 25 invoices to move 1btc.
The max i can pay through my own channel directly to my peer is
"spendable_msat": "4294967295msat"
That limit might be related to the large-channels setting.
Is it the same after switching on large-channels
/ wumbo
in the config?

I have large-channels
enabled. The spendable_msat
is capped at that value on all my channels.
