I know that. I deleted everything and I copied the other 2 mints I had. I did not copy the original mint. That minibits gave me. So when I restored the wallet it asked me to add the mints. I added the other 2. I had to add the original mint as well and I didn't. So the satz from the mint that you provided me restored and the other sadt in the other mint restored. But not my original satz that were in the original Minibits mint that they provided.

Their mint is mint.minibits.cash you can add it yourself. Also, you just need the wallet seed for the backup. You don't need the URL. You only need the URL backup if you are using a browser based cashu wallet.
Restoring the wallet seed should have been enough to restore all your sats and mints.
They must be down or something i even tagged the creator of minibits and atill now answer 🤷🏽♀️
They're also a recovery tool you can try under settings in the wallet.
