I have MASTER-SLAVE configuration on 2 servers. The MySQL replication is set over SSL (I use self-signed certificates).
Everything had been working well. But today some packages (mysql also) were updated via apt update, upgrade. Current version is: mysql Ver 14.14 Distrib 5.7.28, for Linux (x86_64)
Both server and client have the same mysql version now, but slave can't connect to the master. In master's log I see the following error repeating many times:
2019-11-19T16:49:55.109509Z 1130 [Note] Bad handshake 2019-11-19T16:50:55.296184Z 1432 [Note] Bad handshake
What should I check in order to fix this problem? I've already tried to reissue certificates, but it didn't help.
