Hi seco,

I had exactly the same problem.
I don't know why this is happening but the problem is somewhere in the configuration of Apache/Nginx server.
Can you try to login here - http://your_ip:2030/roundcube/?
I login whiteout facing - invalid request no data was saved. But if I try to login with SSL, I have this issue.

Cheers,

RoundCube is working for me over HTTP with no issues. I have standard CentOS 7 fresh install & switch to PHP 7.1.2.

A reinstall might help you.

Hi 6Sense,

Yeah, over HTTP is working (whit IP), but can you try with HTTPS or with HTTP and your hostname?
Unfortunately is not working for me with HTTPS. I reinstall Postfix and Dovecot I few times and is the same. 
I'll find out what causes this problem, but I still thinking is coming from NGINX or Apache config files.

Cheers,

Hi,

I can access RoundCube when I type https://mydomain/roundcube although I just noticed it does forward me to http://myipaddress/roundcube

I have a http > https redirect so can't test http://mydomain/roundcube (it has same result when I typed it in anyhow)
