MySQL Connectivity Troubleshooting | Troubleshooting MySQL connectivity issue due to PERMISSIVE mode. | 95 |

You may find MySQL can't connect after installing Istio. This is because MySQL is a server first protocol,
which can interfere with Istio's protocol detection. In particular, using PERMISSIVE
mTLS mode, may cause issues.
You may see error messages such as ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0
.
This can be fixed by ensuring STRICT
or DISABLE
mode is used, or that all clients are configured
to send mTLS. See server first protocols for more information.
