Here is my situation. I have two web apps one for my main SharePoint site and one for my My Sites. Originally both sites were http:servername:80 and http:servername:(randomport) and I was having no issues searching both from my regular SP site
and MySites. I have since changed my SharePoint site to use a domain cert and changed the AAM to https://sp.domain.com. I have no issues accessing the SharePoint site or searching. I can still use the MySite collection just fine, however
when one tries to search it is pointing back to a search page which no longer exists. I have tried to change this in CA > My Site Settings > My Site Setup and tried replacing what was in preferred search center with the new https://sp.domain.com\search/pages/
however every time I click it wont save my change. I have also tried going into MySite under Site Actions > Site Settings > Search and changing it to enable custom scope to point at my search page that way. I have messed with my bindings,
AAM and host headers to the point where I am just not sure what I need to do. Any help would be much appreciated.
