Gringod "Wallet command failed: LibWallet Error: LibTx Error"

Hey guys,

Running a fresh grin build with grin-wallet and grin-miner on Ubuntu 18.04 LTS. Grin node runs fine, wallet is listening, grin-miner is mining into the wallet correctly, and port forwarding and ufw have been set up.

I’ve been trying to request some test grin from gringod.info but get the following error:
Wallet command failed: LibWallet Error: LibTx Error

Any idea how I can troubleshoot and fix this? Thanks in advance!

Here’s the full output of the ‘curl gringod.info’ command:
