Lost connection - When playing offline HUT

I moved to PS5 a few days ago and I am still getting the issue of being disconnected from EA servers but it happens way, way more than on PS4.

IT says "You have lost your connection to EA servers. Please check your network connection."

Well... I have an extremely fast internet, very stable, and the router/modem sits next to me. If it's down my TV goes off and I see it on the device instantly.

During the day I have many devices connected to my modem/router and my PS5 is connected with a LAN cable. I tried on the wifi and there was absolutely no difference btw.

When this happens, my internet is staying connected to every other device and the speed is normal on all devices at home. Streaming on my computer does not flinch one bit. Even when everybody else is asleep, and all other devices not using data, again no difference.

Also, this only happens when I launch a game offline; challenges or Squad Battles or offline Chel. When I play Rivals I have a different random hexa number error saying I was disconnected. If I try to reconnect right away, works 100% of the time.

So this is 100% a game issue, otherwise it would disconnect me randomly when I am using the AH or building a set, or upgrading my team... or even I would lose connection while in game or in the menus doing nothgin. But none of that ever happened.

It's when I start a game, randomly, and it does not happen when I do anything else. Only as I start a game offline.

Am I the only one having this issue? Is there something I can do to fix it?
