URL problems

Hey, been an avid Gemini user for like a couple days now, and i've been having a really odd problem. I was originally using flash, with the unblocker, but I ran out of messages. It's been a few days, and it still gives me error 429. However, if I turn off the unblocker, and just use google's URL, then it works fine. And if I use pro with the unblocker, it works, anyone elee have this issue? And if so, any fixes?
