I have migrated on SP 2016 environment and configure fresh SSA on same. when I am searching for anything it gives below error
The HTTP service located at http://ServerName:PortNo/9e38a353839448f0b55fe1b52d43fb30/SearchService.svc is unavailable. This could be because the service is too busy or because no endpoint was found listening at the specified address. Please ensure that the address is correct and try accessing the service again later.
When I am looking for Search Service in IIS under the SharePoint Web Service the ID is different from what I am getting in the above error that is 9e38a353839448f0b55fe1b52d43fb30.
I have updated the Search Center URL under Search Settings.
Please suggest useful solution.
