[plankes-projects]

I am connecting to an amazon DB from windows php 7.2.4 with following code:
https://gist.github.com/plankes-projects/d941f49bf74353f0b29700261192c639

I get DNS timeout exception when I am running it on my windows developer machine.

Everthing works fine if I am using this config with eloquent or if I am connecting to a local DB:

Maybe there is an issue because I create my own ClientTlsContext ?
But still does not explain the DNS timeout on local machine.

The problem was indeed my own ClientTlsContext . if I have no CA file and leave ClientTlsContext as null it works on windows server.

Timeout is still present locally.
