Roundcube login failed error can occur due to various reasons that include incorrect hostname, improper ports setup, mail directory incorrectly set, and so on.
Here at Bobcares, we have seen several such Roundcube related issues as part of our Server Management Services for web hosts and online service providers.
Today we’ll take a look at the cause for this error and how to fix it.
What causes Roundcube login failed to occur
Before we get into the solution part, first let’s see what causes this error to occur.
There can be different reasons for this error to occur that include improper ports setup, mail directory incorrectly set, and so on.
The incorrect hostname can also be another reason for this error.
Generally, the server requires an FQDN hostname configured and also wants it to be resolvable in DNS. For example, if the domain name is domain.com then the hostname can be server.domain.com.
So in DNS, there must be an entry for server.domain.com. If this is not available then it can lead to an error.
For instance, the error appears as below.
How we fix Roundcube login failed error
Our Support Engineers provide different ways to resolve this error. Here are some of them.
1. Check hostname
We can do this from WHM
Log into WHM >> Main >> Networking Setup >> Change Hostname
In the DNS section, it will also ask to add an A record entry for it.
Now run the following commands.
#rm -f /etc/userdomains [# /usr/local/cpanel/scripts/updateuserdomains –force
Finally, restart the cPanel service using the command.
#/etc/init.d/cpanel restart
This must fix the Roundcube login error.
2. Check mail directory
Update the Maildir to whatever the system uses.
For that, change Dovecot mail_location setting to
mail_location = maildir:~/Mail
Then change Postfix home_mailbox setting to
home_mailbox = Mail/
Finally, restart services.
3. Check the ports
Make sure to check the ports set in the mail server and reset it (if necessary):
Port 25 (and 587) must be open for SMTP
Port 143 (and 993) must be open for IMAP
Port 110 must be open for POP3
Also, open those ports in the firewall settings.

We were charged almost double what we used to pay and were told that the current service will offer unlimited email space, yet whenever we hit 100M of email space and all mails will bounced back……? When we’re looking for tech support or service, we can’t reach anyone of the company ?
Hi,
Forgot to mention earlier that we were told that our mailbox was 99% full…..? you may not even be able to send email there…… ?

When I originally left a comment I appear to have clicked the -Notify me when new comments are added- checkbox and from now on whenever a comment is added I receive 4 emails with the same comment. Is there a means you are able to remove me from that service? Thanks!
