Redirect Loop on Wordpress site with IP adress as Domain name

To preface my problem, I am using my droplets IP as site address. Nothing have become a problem for this 3 month, until 2 days ago. Suddenly my site can’t be opened with ERR_Too_Many_Redirect message.

Using link redirect trace i’ve found that my site seems to keep redirecting into itself. Because it’s not the first time i came across this problem, but it’s the first time when using DigitalOcean VPS, I usually just change the content of wp-config to fix this problem.

But because this seems to have no effect in this issue I have come to ask for some advice.

This is what I’ve done up to this point -clearing cache, cookies etc from my browser and Wordpress -Fix wordpress url through wp-config -change, deleting, and make a new .htaccess file -deactivating and deleting plugins -restore the droplet from pre-incident backup

It might have been http to https redirect loop. But I doubt it because I make the redirect 3 months ago and never come to any problem. and while i just renew my SSL Mid-April from Zero-SSL. I don’t think it will be an issue.

Any advice is appreciated, thank you
