A few days ago, in a restart of the server machine, the mysql connector was unconfigured, at that moment ‘ **mysql-connector-java-5.1.15-bin** ’ was installed, in the next restart of the machine the gateway no longer wanted to start, any possible solution? Or will it be better to reinstall ignition and how should I do so as not to lose projects, tags, …?

Hello,

When troubleshooting issues like this we scrutinize the actions that lead up to the Gateway breaking.

Based on your notes you restarted your Gateway and then updated a MySQL driver. Did you upload the jar file through the Gateway Webpage as described in our documentation?  
[JDBC Drivers and Translators - Ignition User Manual 8.0 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC80/JDBC+Drivers+and+Translators)  
If you uploaded a file that was not the .jar file to the MySQL driver it could cause problems.

You can go check in your Ignition directory under user-lib/jdbc and ensure there are only Jar files in that directory. Deleting the mysql-connector file in this directory may let you start the Gateway.

I would recommend getting in contact with [Inductive Automation Support](https://inductiveautomation.com/support/home/) if you are still unable to start the gateway.
