Can't log in on Minecraft Bedrock Edition

It will not let you log in at all and say error code Drowned. And on the launcher it makes you log in 3 times, then a fourth time when you launch Bedrock. I have clicked on “More info” button and read it but I when read it said to log out and log back in but that didn’t work then it said to repair and reset the launcher but I really don’t trust that will work and I don’t want to lose my 1100+ day world. I have made backups but I don’t know if it will get deleted too. I would really to find a way to fix it without deleting my save data.
