MySQL issue with Core2024.3.0

[MasterCATZ]

The problem

I just did an HA update today and now MySQL refuses to allow connection
no passwords or host names etc have been changed mysql settings have not been played with

mysql://user:password@SERVER_IP/DB_NAME?charset=utf8mb4&ssl=true

[Warning] Access denied for user ‘homeassistant’@‘homeassistant.fritz.box’ (using password: YES)

its a Galera Cluster  with offsite replication 

Core2024.3.0
Supervisor2024.02.1
Operating System12.0
Frontend20240306.0

and after about 100 restarts using quick and full trying to change config combinations and even full power off / on , gave up and rolled back to a part backup from 10 hours ago

Core2024.2.5
Supervisor2024.02.1
Operating System12.0
Frontend20240207.1

and it connected again somethings up with Core2024.3.0

Additional information

I have seen others having issues with ssl no longer working ie) can not use webmin anymore can no longer remote in

[ulf-melin-sveasolar]

I have basically the same experience, mysql connection did not work after installing core 2024.3.0, but started working again as soon as I rolled back to 2024.2.5

I am using Raspberry Pi 3b installation and a mysql in Azure, with ?ssl=true

[dkrebs]

Not sure it it's the same problem, but after upgrade to Core2024.3.0 recorder also stopped working completely for me.

2024-03-08` 08:02:13.808 WARNING (MainThread) [homeassistant.setup] Setup of recorder is taking over 10 seconds.
2024-03-08 08:03:01.866 WARNING (MainThread) [homeassistant.bootstrap] Waiting on integrations to complete setup: recorder
2024-03-08 08:04:01.969 WARNING (MainThread) [homeassistant.bootstrap] Waiting on integrations to complete setup: recorder
...

When enabling debug mode there is no more information about the issue.

ok, this was probably unrelated - my MariaDb version seemed to be too old

[ivercellino]

I think something has definety changed in 2024.3.0 regarding the database conenctions.
I have more than 60 sql sensors configured with the standard sql integrations connected to a MariaDB running on the same Raspberry4.
After the upgrade most of them have become unvailable right from the startup in a random way.
Sometimes reloading helps, sometimes not.
Reverted back to 2024.2.5 and everything is fine again.

So obviuosly something is not running smoth with db connections.

[flechaig]

Same issue here:
ERROR (Recorder) [homeassistant.components.recorder.core] Error during connection setup: (MySQLdb.OperationalError) (3159, 'Connections using insecure transport are prohibited while --require_secure_transport=ON.')
Works fine in 2024.2.5.
I think it's an issue with SSL/TLS but can't tell more details for now.

[home-assistant]

Hey there @home-assistant/core, mind taking a look at this issue as it has been labeled with an integration (recorder) you are listed as a code owner for? Thanks!

To give further details on my issue: I upgraded to 2024.3.0 and everything was okay for a few days. Then I noticed I couldn't pull any log or recorder history for entities.

I checked my NAS, where I store my HA recorder history, and the entire database was gone. Nothing changed on my NAS side of things either.

I have no idea why the entire database would be deleted and I've never had this issue before

I decided to try again and updated 2 days ago.

So far, its going well, but I think this is the same experience I had before it deleted the whole database.

[MasterCATZ]

guess its a good thing my db denies it then , I might have to start doing archive backups then
currently I just have a offsite Galera Cluster , tho they are on a ZFS FS so I guess I could still roll back

Hi,
I solved my own issue (may not work for everybody).
Due to changes in the mysqlclient Python library (starting 2.2.2), the parameters of the connection string must be adjusted. I added ssl_mode=REQUIRED and the connection is back again in HA 2024.4.0.
See PyMySQL/mysqlclient#700 for details.

Your MySQL connection string should look like something like this.
db_url: 'mysql://<user>:<password>@<server>/<database>?charset=utf8&ssl=True&ssl_mode=REQUIRED'

The help page should be updated to reflect this new requirement.
