In reply to Wouter Samaey. @Wouter a cron process generally wouldn't reuse the same connection as one from your web server. Most likely, your web server has a processes that handles one request after another. The process will try to re-use a connection from a previous request.

I am seeing this error in random web requests when I haven made a request in a few minutes. I’m using persistent connections. Could the issue be that the web request uses a connection opened by a long running cron PHP process making the DB connection not as fresh as you’d expect?

In reply to K A. Looks like it is related. MySQL mad some changes around 8.0.25 relates to SSL Ciphers and it sounds like some other connection related code that sounds like it introduced this and the mysqlnd PHP libraries are awaiting an update.

Have also been wrestling with this issue (after migrating from Aurora 5.6 to MySQL 8 recently!).

Seems to be related to this bug in PHP:
