InternalServerError: Cannot complete OAuth process. Could not find an OAuth cookie for shop url

[Lancer1989]

I built the Shopify app according to the official case. I tried to use the nginx reverse proxy instead of ngrok to work. The first installation was successful and it worked normally. But I found that no matter how many times I clicked it, the error message "InternalServerError: Cannot complete OAuth process. Could not find an OAuth cookie for shop url." appeared. After inquiring, I could not get the best solution.
How can I avoid this problem?
