TrueNAS : Error to first login page

[C4rter]

Hello there,

i just installed Roundcube application on my NAS TrueNAS. All seems ok but when i try to login to my RC WebUI i 've systematicly an issue "error login to storage server"

I made a standard installation without change anything exept informations about my mail servers IMAP & SMTP
Can uu help me please ?

"error login to storage server" suggests your IMAP server refused your login. That could have nothing to do with your Roundcube installation. Try enabling `imap_debug` in your Roundcube config, repeating the error and then checking the log file to see the communication between Roundcube and your IMAP server or check your IMAP server logs to see why authentication failed.

This is the problem, PHP could not resolve your imap server address. You appear to have a DNS issue.
