Sorry to hear this @Brusim

It may be a temporary network/ISP-related issue. If you’re able to temporarily switch to a mobile data connection and check if the errors persist, this can help to determine this.

Otherwise, our general connectivity solutions may be of help, here:

Specifically, restarting your router and flushing your DNS would be a good starting point.

Please let me know how you get on!

Just tried restarting the router. It didn’t fix that but changing from the 5.8 GHz to the 2.4 GHz seems to be a temporary fix for it.
I’ll keep in touch if i get any more information.

I’ve been getting a lot of the same errors, which kick me out of the game. And I see we get the same level of support from FS as usual. I also have seen an increase in getting stuck in the Raptor “Reading Data From Disk” and sometimes “Waiting For Other Players”. It’s pretty frustrating that the issues exists, and nothing but try these generic tasks and Have A Nice Day type responses.
