can somebody help me figure out why?

You can check the log HTML file generated by HFSS in its main folder. It provides a summary of the problem and you can easily trace it. I'd guess you have some vertex that is not in order - for instance 3.000000001 and your port is at position 3.00000000. Sometimes it is very annoying but once you are used to use grids it is easy to fix.
Yet for definitive answer check the HTML error report. If you have problems send it to my e-mail and I will have a look and possibly advise.
