Hello everyone I have a problem with accessing Roundcube Mail, that is when I look for ip address / webmail I access the login screen without problems but when I search with the domain of the site / webmail I cannot log in and it returns the error 500 the page doesn't work. Thanks to those who can give me a hand.
