"Transaction not found" for pending channel

While one channel was opening/pending, I opened another. That one seems stuck. When I click on the transaction ID, I see on mempool.space I see “Transaction not found. Waiting for it to appear in the mempool…”

It’s been like that for about 36 hours. Is there a way I can abort and re-try? I once was able to increase the fee on a transaction using Ride the Lightning, but this transaction seems to not exist. So, I don’t think I can do the replace-by-fee or child-pushes-parent things.

Thank-you for any help you can offer!
