Hi,
I am seeing below error while trying to login to Roundcube after installation. Telnet to port 993 is working fine. Dovecot is running without any issues. Trying to resolve this issue since 2 days but could not able to fix it even after trying all the recommended solutions provided in earlier discussions.
