Hey, this is generally due to an outdated database (v2.1.1 requires the version 2 db). There are two methods to upgrade but the first will require ~200GB free on the drive that contains the database:

Steps for the CLI command:

1. Stop the chia client (this can be done while chia is running but stopping the client saves from any potential issues)
2. Run the command `chia db upgrade` (you do not need the input or output paths if these are still default)
- This process will take some time and requires additional space as the v1 db is compacted into the v2 db which leaves the v1 db intact
3. Verify the config file (~\.chia\mainnet\config\config.yaml) has the correct value under the full_node section for `database_path: db/blockchain_v2_CHALLENGE.sqlite` (should only need to change the v1 to v2)
4. After the above completes start the chia client
5. If all loads up properly (might take ~5-10 minutes to load) then you can safely delete the v1 db found here (~\.chia\mainnet\db\blockchain_v1_mainnet.sqlite)

Steps for using the torrent:

1. Download the torrent file from https://www.chia.net/downloads/#database-checkpoint
2. Use a torrent client to download the full db
3. Unpack/reassemble the torrent file that was downloaded (on windows I used 7zip, Mac and linux have built in tools that work for this)
4. Stop chia then move the db to the correct folder (~\.chia\mainnet\db\) and update the name to "blockchain_v2_mainnet.sqlite" (removing the date information in the name)
5. Verify the config file (~\.chia\mainnet\config\config.yaml) has the correct value under the full_node section for `database_path: db/blockchain_v2_CHALLENGE.sqlite` (should only need to change the v1 to v2)
6. Launch chia and wait for a bit (the height to hash and peers files need to be built so this can take 5-10 minutes)

If you are still experiencing the issues it is recommended to upgrade to the latest version of chia. Please download it from here: https://www.chia.net/downloads/

Since this issue has been open for a number of years without additional comments, we will be closing this ticket but if we have closed this ticket in error do not hesitate to reach out to us again with any followup questions, comments, or if the issue persists after an update.

Please note that upgrading major versions of chia generally requires the config.yaml to be recreated using these steps:
1. Stop chia
2. Rename the config or move it to a different directory
3. In CLI run chia init
4. Copy any custom settings from the old config to the new (plot drive directories, pool info, trusted node info, etc) - be careful here as yaml is very picky about formatting including those leading spaces
5. Start Chia
