Github not working on brave version

I’ve noticed this recently that doesn’t load most of the times, some times it just loads but really slow. I don’t know if this is a bug or something else.
I’m on ubuntu 20.04 LTS

$ brave-browser --version

The above is I feel the version of brave I’m using which is I think the latest.

I thought this might be something to do with github servers, but on firefox it loads normally and I can git clone things easily.

If there is something I might be missing out, please let me know.
