Why isn't my Email syncing on WIFI at home only on Note 5?

Email not syncing on WIFI at home only on Note 5

My Note 5 can't sync one of my email account on Wifi at home.
Funny thing is that all my other accounts work, also the bad Wifi at works fine for all accounts.
Help anyone?

It worked for a few days when I just got the phone.
