The terribly slow start up of FCP

My FCP starts up really slowly. It takes an age to load and when it finally does, a strange screen pops up. At first, this screen used to only appear while starting up, but now, it just appears randomly for no apparent reason, when running FCP.
I am using an external hard drive. I copied the files to the local drive. I thought of looking for some form of render file. Please see the image below.

Connection failed: The server ''(fe80:4:0:0:20d:93ff:feb 1:e882)'' may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again.
OK.
