Andrew there is the possibility that ip routing is not enabled or a setting that prevents devices talking to each other. I can't confirm from my resource however  since I can connect on two other networks please consider my issue closed.

Thanks for your help!

My Mac is 172.30.75.34 255.255.255.0

My iPhone is 172.30.75.40 255.255.255.0

Router and DNS on both are 172.30.75.1 8.8.8.8

I am running into the same issue, unable to connect over wifi or direct connection at work. I created a new user which also did not resolve the issue.

I am able to connect on my home wireless.

I am able to connect if I start up a personal hot spot on my iPhone.

I am not able to connect on our work wireless or using the direct connection to the Alfred server.

I did notice when connecting to our wifi that the cert was out of date and agreed to proceed. Not sure if it would help but I went into the apple keychain and checked that all parameters for the cert were set to trusted. No luck though.
