errors problem all time

hi there, 
i just installed em client and i logged into my gmail, but the problem i can’t see any of my messages. the contacts and calendar were successful synchronous.

every time i open em client it tells me:
[IMAP] an attempt to connect to “my email” failed. This could be cussed by temporary server unavailability or incorrect settings. Do you want to check the settings ? 

Option 1 : Ignore.
Option 2 : open account settings. 

i don’t know how to fix it can anyone help please?
