Welcome to Europe and it slow networks.
However just been down the pub, Beer Keller!. They have Wi-Fi 6, not wifi 4 standard.
Looking around Fortnite Creative my Matchmaking is set to auto United Kingdom which sets the servers location.
Check your Matchmaking servers are not set to Asia and USA, you might be using EMEA server, but are you using the servers in London and Galway, Ireland Global Infrastructure - AWS (amazon.com)
UEFN gathers all its information from Fortnite Creative. There are many things on Android and Xbox versions that are not available in UEFN
You can test you network by taking a phone and finding a WiFi 6 at a Costa Coffee shop on large brewery . The number 6 appear in the wireless icon connection.
Update
Taken laptop to same Wifi 6 network used on phone and now found my laptop only supports
only support 802.11ac where as
most Android phone support 802.11ax then it’s Wi-Fi 6 ready
but why should this make a difference?
Ouch
Same here… As a workaround, I got a Virtual Machine on Shadow.tech and from there I have no connection timeout problems. Expensive, not ideal, but it works.
Check your internet connection and restart your device, it should do the trick and, also, peek at fortnite’s social media for any updates on the server issues
This instruction worked for me more or less! Well, except I noticed my Windows automatically blocking or prompting me to allow certain network connections even though I’m on my own home WiFi network.
I went to the Windows Defender firewall advanced info area, and I saw some games like Fortnite had some red “block” markers next to them for when the computer is on public wifi. I disabled those rules and now I can connect without issue so far. For me it feels like a recent Windows update or something related made changes that messed up Fortnite being able to connect when a session was started from the editor.
Before this when I was trying to connect, I tried verifying the UEFN files and Fortnite files from the Epic Games Launcher, but the issue happened after that until I tried this.
You can see in the Windows Defender firewall rules where I changed it in the screenshot:
