Getaddrinfo failed: Name or service not known

Wappler Version : 3.0.1
Operating System : php 7.3.11

The following error is appearing on a project when calling a server connect action. It SEEMS to occur on the first hit only, as hits after that all work until I leave the project and come back to work later. The server is attempting to connect to a remote database server at digital ocean.

I suspect it is a digital ocean issue, but posting here in case Wappler is not waiting long enough for the connection or something.

Any ideas?
