multifundchannel - some channels are stuck at CHANNELD_AWAITING_LOCKIN until reconnect
Issue and Steps to Reproduce
Hi, I've opened a multichannel using this code:
lightning-cli multifundchannel '[
{
"id": "03cfea6e01d8735d29863d0ecc0f637e5da25c3afb1894e6cb1c25cc9c52dbceef",
"amount": "1500000"
},
{
"id": "03f15fc38f36e88bf1d799994d38e10902318287a53eb413b5e8ab0046d863bace",
"amount": "1500000"
},
{
"id": "02c197ffa4c2aa4105dd4c4b7279ba1b9061b22910ebbfa759b0001bed9ee48a16",
"amount": "1500000",
},
{
"id": "032ebdae3314f072acd70e66e18572e6ba27f96918009369585e7cdcf36af3cf9e",
"amount": "1500000",
}
]' 1000perkb
2 of the channels were verified correctly, but the other two were stuck on CHANNELD_AWAITING_LOCKIN. Once I disconnected (e.g. lightning-cli disconnect 02c197ffa4c2aa4105dd4c4b7279ba1b9061b22910ebbfa759b0001bed9ee48a16 true , see below) from one of the problematic peers and then reconnected, the channels instantly became active
Here is a full terminal output for the commands that I ran:

I also have DEBUG log file if needed. @rustyrussell might be related to this - https://github.com/ElementsProject/lightning/pull/2776 ?

Good thing you posted this issue, had a channel in state 'waiting', instantly confirmed after disconnect command.
Thanks!
I can confirm this on v23.08-modded: 1 of 2 multifund channels stucked in CHANNELD_AWAITING_LOCKIN: Sent reestablish, waiting for theirs immediately turned into CHANNELD_NORMAL when I reconnected to the peer.
