I deauthorized Netlify from my Github but re-authorized it again. How can I get the Netlify deploy key so that I can re-add it to my Github repo? It was auto removed when i deauthorized Netlify.
Alternatively, you can just edit your current site and change the origin, and link it to your GitHub account again.
There are 2 solutions depending on your urgency:
Create a new site on Netlify (or delete and recreate your old one) and link it to Github again.
Email Netlify support to get the deploy key to add back to your Github.
