Using RM 10.0.5.0 and Windows 10.
Attempting to connect to FamilySearch for webhints, and I receive a Connection Error box that says ‘Unable to open the port to complete the sign-in with FamilySearch. Please check your internet connection and firewall’. The box has two button for ‘Retry’ and ‘Cancel’.
It then tries to connect to FamilySearch which fails and my browser then says it can’t establish a connection to localhost:9717 which fails.
I have reinstalled RM and made sure except that RM has access through the firewall. My internet connection is fine, I can access any site outside of RM. I can also access FamilySearch. Ancestry is still working just fine from within RM. FamilySearch works fine outside of RM.
I seem to recall something like this happening in version 9, for which there apparently was no known cause, nor did it ever seem to be acknowledged that it was a problem
