Too many redirects issue

Hey guys!!

I am new here. Running Plesk on Nginx, works great! Just been running into issue today I cant seem to figure out. I have few static websites and then some WordPress sites running on my server. Today I noticed the WordPress sites keeps redirecting and eventually just show error page "too my redirects". From my experience with WordPress its normally the htaccess file causing these problems but doesnt seem to be in this case. Any suggestions on what other troubleshooting steps I can try?
