I get the same reservation timed out issue when I play on my main account. I have reinstalled the game on steam and on origin, I have rebooted my router countless times, flushed my dns and followed multiple connectivity troubleshooting guides without any results. I tried changing data centre multiple times too.
I tried playing on my other low level account and it worked perfectly. I never had any issues with apex ever.
I messaged EA Help on Twitter, they didn't really help, they said they would " keep monitoring the issues, and try to fix it if it's still a thing in the future " something in these lines, they also don't refund the battlepasses we bought but can't up since we can't play, quite the winners...
