TikTok saying “no internet connection”

So I came back from Cuba yesterday(I’m a flight attendant)and once I landed TikTok stopped working for me. First I could see videos but no comments or give likes, then I couldn’t see videos o comments but I still had the sound and now I can’t even see my own page. Everything says “no internet connection, try again later”. Well, I updated my software, downloaded the app again, and made sure I have Cellular Data ON. At this point idk what to do🥲.
Anyone has any tips or maybe has any idea what is going on?
