"<Player> has not played on the server before." error due to improperly set `server_ip` in `ah_bans`

[RalphORama]

I am running an offline mode server behind a Velocity proxy.

A player died, and was deathbanned. However, when I run the command undeathban Brohammad, I get the error Brohammad has not played on the server before. I am not sure why this issue is happening. Upon inspecting the database, I see the following:

SELECT player_uuid,last_known_name,last_death FROM ah_player WHERE last_known_name = 'Brohammad';

-- +--------------------------------------+-----------------+---------------------+
-- | player_uuid                          | last_known_name | last_death          |
-- +--------------------------------------+-----------------+---------------------+
-- | 970e5b2b-4326-41b8-bdb8-0f5e5ad49e85 | Brohammad       | 2024-02-14 17:27:01 |
-- +--------------------------------------+-----------------+---------------------+

SELECT ban_id,player_uuid,server_ip,server_port,start_date,expiration_date,ban_time FROM ah_ban WHERE player_uuid = '970e5b2b-4326-41b8-bdb8-0f5e5ad49e85';

-- +--------+--------------------------------------+------------+-------------+---------------------+---------------------+----------+
-- | ban_id | player_uuid                          | server_ip  | server_port | start_date          | expiration_date     | ban_time |
-- +--------+--------------------------------------+------------+-------------+---------------------+---------------------+----------+
-- |      1 | 970e5b2b-4326-41b8-bdb8-0f5e5ad49e85 | 172.18.0.4 |       26602 | 2024-02-14 17:27:01 | 2024-02-15 17:27:01 |     1440 |
-- +--------+--------------------------------------+------------+-------------+---------------------+---------------------+----------+

Old bans (from before I set up Velocity) have NULL set for server_ip and server_port. I tried updating those fields:

UPDATE ah_ban SET server_ip = NULL, server_port = NULL WHERE server_ip = '172.18.0.4';

But this did not fix the issue.

EDIT: I found a fix for the issue.

Running the UPDATE query did not fix the issue while the server was online. When I shut the server down it updated the rows again. I shut the server down, ran the UPDATE query, and started the server again. This fixed the issue.
