Question

unsupported frontend protocol 1234.5680: server supports 2.0 to 3.0

but when we start confluence with version 7.9.1 , postgres container will throw above logs.

Anyone know how we can resolve this since we tried PGGSSENCMODE=disable in env but it didnt help.

We resolved this by using new postgresql-42.2.18.jar which we replaced with postgresql-42.2.16.jar

suggested here : https://jira.atlassian.com/browse/CONFSERVER-60515?error=login_required&error_description=Login+required&state=14f30dda-a08b-4f9d-9841-ed77c8e91c79

Thank you for your support.

For those who are using postgresql-42.2.16.jar or prior and are looking to quiet this error without upgrading the JDBC jar, you can use the following option in the connection string - note case sensitivity:

gssEncMode=disable
