I have SunOS and I am trying to connect from Studio 3T on Windows. I cannot connect and get the following error in the log:
Database error(MongoIncompatibleDriverException): Server at xx.xx.xx.xx:27017 reports wire version 0, but this version of the driver requires atleast 1 (MongoDB 2.6
Studio 3T upgraded to the latest 3.6 mongo driver back in December 2017, which seems to have dropped support for MongoDB 2.4 (it reached its End-Of-Life in March 2016: https://www.mongodb.com/support-policy).
With this change, Studio 3T then currently supports MongoDB versions 2.6 - 3.6.
