Crash when recovering 2of2 wallet

Ran garecovery-cli as shown in the example to recover 2of2 CSV wallet.

OS is Ubuntu 20.04.3 LTS with a freshly made Bitcoin Core full node with only a single wallet, which is active configured for RPC (username rpcuser, password rpcpassword to match the values bitcoincore.py)

It runs for about an hour and then crashes with the following. CSV file is 0 bytes. Confirmed I can communicate with the local RPC server.

Things I have tried:
- Found out by reading the error logs and then bitcoincore.py that you must use the default rpcuser and rpcpassword
- Specifying 127.0.0.1, which gave me an error it couldn't talk to 0.0.0.0
- Applied an rpcauth string of rpcuser / rpcpassword according to https://jlopp.github.io/bitcoin-core-rpc-auth-generator/ - no idea if this is even correct?
- Commented out the rpcauth line entirely - no change in behavior, so assuming it's not needed
- set server=1 in bitcoin.conf to allow command line and RPC commands
- Verified my wallet is loading correctly
- Confirmed RPC connectivity with bitcoin-cli getblockchaininfo
- Making sure port 8333 is open for Bitcoin Core, then closing it intentionally to see if the output of gaercovery-cli was different (it wasn't)

Am i doing something wrong? I have been trying various configurations getting everything to work together for about two days, but I haven't been able to have any success, which is very discouraging.
