Unfunded Error Despite Retaining 20 XRP

[sajdutts]

For the last few months, I am trying to get my XRP out of Toast Wallet but keep getting the 'tecUNFUNDED_PAYMENT' error. Here's my Toast public address that you can look up to see: tecUNFUNDED_PAYMENT error.
rLtx5RKuf2gYo5QP4fmwBWFTpGh9vtvirN

Please don't ask the obvious: yes, the address was correct. I even tried sending to different addresses with the correct tags. Yes, 20 XRP was left to Toast. I even tried sending just 5 XRP which worked before. You can see all those logs if you go to:

Any idea?
