I don't see a particular reason why it takes 30 seconds in your case but you never know with these DB providers. Some of them might not even implement ConnectionTimeout. What provider do you use? Let us see the connection string. Expand Sorry you're right, it takes 30 seconds only when both servers fail Im using Sql server express 2019 you can see the connection string in my post above Edited August 2, 2023 by Holy_Boy Sorry if my grammar isn't proper, English is my third Language...
Andreik Posted August 2, 2023 Posted August 2, 2023 (edited) This should work.

After 2 seconds (since first connection fails on purpose) or so I managed to connect to localhost as expected. Give it a try. Edited August 2, 2023 by Andreik

Andreik Posted August 2, 2023 Posted August 2, 2023 Another wrong part is to set ConnectionTimeout after the attempt to connect to server. It should be set before and just one time since it's a persistent property.

Andreik Posted August 2, 2023 Posted August 2, 2023 ConnectionTimeout should be set before a connection attempt is made. And you don't have to set it for next _SQL_Connect() calls if you don't want a different timeout. _SQL_ConnectionTimeout(-1,2) $server1=_SQL_Connect(-1,$server,$database,$username,$password)
