Files and timeout message too long

Hello

I am using Gnome under Manjaro and the “Files” application is showing me a message that the timeout is over.
And for good reason, it’s about displaying the contents of a folder on a local server (NAS synology and a very old and rather slow D-Link)
I’m not sure if there is a way to extend the time between the start of the opening command and the message.
Thanks
