I’ve definitely heard bad things about Oracle deleting people’s machines without warning. Unfortunately I don’t know anything about Ionos. I may go with Linode, their cheapest VPS at $5/month has a 1TB transfer limit, which I might stay under. But please let me know if you end up finding a decent option from a reliable company!
I had a similar problem that ended up having to do with my server’s language settings. I didn’t realize you can select more than just “Undetermined” by holding down shift or ctrl. So everything tagged as English didn’t appear until I went back and fixed it. You can read the whole odyssey here: https://lemmy.ml/post/1205767
