Is there an existing issue for this?

I have searched the existing issues

Current behaviour

Using bitcoind 28.0 I wanted to setup a new full node and load the utxo snapshot from loop.net. I got the following error.

$ bitcoin-cli -rpcclienttimeout=0 loadtxoutset   utxo-snapshot-height-840000.dat 
RPC password> 
error code: -8
error message:
Couldn't open file /appdata/bitcoin-01/data/utxo-snapshot-height-840000.dat for reading.

Expected behaviour

Should load

Steps to reproduce

The file is rw. Maybe the download is corrupt, but I have no sha256sum to compare

Or there is something special with my config

debuglogfile=/appdata/bitcoin-01/var/log/debug.log

It looks like the snapshot you are trying to load is not in the data directory. Either move it there, or provide the full path to the file in the command. If you just pass the file name, bitcoin will attempt to load it from its data directory (as indicated by the error message).

Thank you. I did not read the error message correctly.
