can't log into realm

I had an update to my realm called HamburGEISHA today and my realm is now saying that the realm needs an update and i will too. Then it says too check store. When i do there's no new updates available. Is this an update you do on your. End? I see the realm is still on 1.18.2 is that correct? Please help i have multiple people reaching out to me complaining they can't get into the realm.
