We are usung VDF19.1 and Meretch Flex2SQLSql. Werecently had cusomer site where a security update removed TLS 1.0 and TLS 1.1 from the SQL server. Our Webapp would not then restart. We had to reinstate The obsolete TLS protocols to get it to work. We login automatically for the user with:

Login sServerName sUsername sPassword sDBtype

and it all works until you switch of the old TLS protocols 1.0 nd 1.1 then it fails to log in to the SQL server.

I would have thought it was definitly the driver at fault but the odd thing is Database Explorer will allow a Mertech login and connect to the database. Anybody seen this behaviour or knowwhere to start looking?
