After reading some online guideline, I tried changing my Magento admin url.
I found it at Stores-->Configuration--> Advanced-->Admin base url.
I decided to change the admin url but didnt include the "/". Now my admin urls(both old and new) returns a "404 NOT FOUND" page.
Already tried using ssh commands but to no effect including:
php bin/magento setup:config:set --backend-frontname="magento".
I need help correcting this error. My current magento version is 2.1.9
