Hi, see if this helps: https://stackoverflow.com/questions/64210167/unable-to-connect-to-postgres-db-due-to-the-authentication-type-10-is-not-suppor
I think you should change configuration in pg_hba.conf of postgres Get your pg_hba.conf File […] And Simply Change scram-sha-256 under Column Method to trust. , or change the jar with postgresql driver in the Guacamole lib directories… According to the wiki<https://wiki.postgresql.org/wiki/List_of_drivers#Drivers>, the supported JDBC driver for SCRAM-SHA-256 encryption is 42.2.0 or above. In my case, the driver was 41.1.1. Change it to 42.2.0 or above. That fixed it for me. Regards.
