New Lightning Channels Stuck on Open

Well I’ve given this a try and have unfortunately not had any luck. I receive the following error message:

The Passed Output Does Not Belong To The Wallet

Digging around on the internet reveals that one solution is to increase the mempool size and then republish the transactions.

I don’t think that this is possible with Umbrel inbetween me and the config options, but wanted to ask if there’s a way to do this or a different solution for Umbrel users.

Thank you!
