Get "Cannot connect to Server" message when checking yahoo email account

My yahoo email account won't update with new messages as of two days ago. I updated my iphone 6 to the latest IOS - 8.3.1 today and it had no affect on the issue. I reset my phone, deleted and re-added my yahoo email account several times and started getting a message - "Cannot get Mail - connection to the server failed". I had deleted and added my yahoo email account through the yahoo mail wizard (Settings/Mail,Contacts,Calenders/Accounts/Add Account/"Yahoo")- so as a work around I added the email through the : Settings/Mail,Contacts,Calenders/Accounts/Add Account/"Other" - this method worked in that I added my yahoo email account and i manually entered incoming mail server host name as "imap.mail.yahoo.com" which allowed the IOS mail program to connect to the yahoo mail server for incoming emails. The downside is that it doesn't allow me to have my contacts, calendars, reminders from my yahoo mail to be seen/synched as it does when you add it through the Yahoo wizard.

The other observation I had with regards to this issue - is my Ipad 2 did not experience any issues with my yahoo email - i was able to check all my latest emails, etc. with no updating issues. I have not updated my ipad to the most recent IOS 8.3.1

Has anyone experienced this and does anyone else have a solution? It appears that the wizard somehow has a bad link/address for the incoming mail server based on my work around solution.
