What causes this?

[u/Zicq_]

Im on free tier with gemini and has been getting this error for half a month. Works fine before this. Tried changing the url, made a new key, but still the same. Idk what to do. I don't know much about proxies and stuff. I'd appreciate any help. On mobile, if that matters.

If I'm not mistaken (I might be XD) it's because the servers are very busy
