App store app giving error msg "ConnectionManager::invoke::Failed to find service connection url." when using correct passord

Hi,

I'm using the correct apple id/pwd. I get this error msg:

ConnectionManager::invoke::Failed to find service connection url.

Too many tries forced me to change my pwd. Using new pwd, still getting that error msg:

ConnectionManager::invoke::Failed to find service connection url.

Am trying to re-download purchases I lost due to needing to do a clean reinstall to correct some mystery issue. I was able to re-download some such old purchases the other day--but not now.

Any help much appreciated!
