Can't connect to server for upload

[Gary Reimer]

When I start the upload to FileMaker Server and it asks for me to enter my Admin Console name and password, I get "Connection failed." I'm using the same name & password that I use to log into the server console where it works. I have uploaded many files in the past but now it won't work. 

I'm using:
Mac OS X 10.11.4
FileMaker Server 14.0.4.414
FileMaker Pro Advanced 14.0.5

Thanks
Gary

Hi Gary,

Please update your profile to reflect your current version of FileMaker and OS.

Double-check that port 443 is open on the FMS box.

[David Doscher]

Hello, I am having the same issue, (same software versions but OSX 10.11.7) and I have verified that nothing is using that port. SSL is turned of in the FMS console. Firewall is turned off on FMS machine.  I can connect all day long to open databases, but connection fails when I attempt to upload.

Do I have to create an explicit rule for 443?
