WARN: Establishing SSL connection without server's identity verification is not recommended

[Hyd3k]

Hi community, I suddenly received warnings when trying to start a Jira instance (CentOS 7x64, Jira 7.8.1). Instance was working fine but now does not, I remember I updated mysql server 2 days ago but until today I restarted server/Jira instance and noticed this error that will not allow me to start Jira.

Can you please help?

According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

I tried following similar topic but still unable to run Jira:

https://community.atlassian.com/t5/Confluence-questions/SSL-Warning-filling-catalina-out-when-connecting-to-MySQL/qaq-p/117867.

I added:

&useSSL=false

&useSSL=false

?useSSL=false

to /var/atlassian/application-data/jira/dbconfig.xml

We have seen in the past that this has worked for some customers. It is just the syntax that needs to be followed. In their cases, they have added the useSSL=false as a suffix to the Jira URL.

You can refer to the community document this might help you. If this doesn't then reach out to support.

Hello team! We have the same issue. In the catalina.out logs have 
{code:java}

nevertheless in dbconfig.xml I have the next configuration:
