email connection timeout does not show up with email-check on admin dashboard

[s-light]

i have setup Phraseanet with docker on a old laptop to test it.
the basic web-app does work.
but i wanted to setup mail so i can also test the new user mail feature.

for this i put my mail config into the .env

# Phraseanet mail configuration
PHRASEANET_EMITTER_EMAIL=cloud@myotherdomain.eu
PHRASEANET_MAIL_OBJECT_PREFIX=
PHRASEANET_SMTP_ENABLED=true
PHRASEANET_SMTP_HOST=xxxxxx123456789.mailout.server-he.de
PHRASEANET_SMTP_PORT=465
PHRASEANET_SMTP_AUTH_ENABLED=true
PHRASEANET_SMTP_SECURE_MODE=tls
PHRASEANET_SMTP_USER=usernamething
PHRASEANET_SMTP_PASSWORD=mypassword

but if i go to the admin dashboard and use the test mail form i get som errors in the logfile and the site does get empty:

so likely that the connection is not working is a configuration error from me...
i think that the server does not handle this error crasefully and reports this problem back to the dashboard is a bug?! :-)

Hello,

It seems like you're facing a network dns resolution matter from the container side.
Can you make sure by entering into the phraseanet container that you can resolve any dns name.

Best regards

thanks @moctardiouf. i think i have tested for dns resolution - but will revisit at the weekend..
my main point was: if this kind of error happens it would be a good idea to show it to the user interface instead of a white nothing.... ;-)
