Did you try using a simple vpn? Tons of stuff blocks tor nodes now due to abuse. It’s disappointing, but not impossible to understand.

Would using a VPN to sign up for an email over Tor (provided you could) afford you better or worse privacy?
VPN + Tor is practically the same as just using Tor, the difference being that your ISP no longer knows you're using Tor (they just know you're using a VPN) but you vpn provider knows you're using Tor.
From the perspective of the website, you're using Tor in both scenarios.
I use Tor with a VPN just because I don't want to bother turning the VPN off but I know it makes absolutely no difference in my experience.
