Hi nmason12,
In that case, since the same issue occurs with other Wi-Fi networks, we'll take some steps to ensure your iPhone is set up to use Wi-Fi networks without issue.
First, let's go into Settings > General > Date & Time and turn off the option to "Set Automatically". After about 20 seconds, or if it's already off, please turn it on again, and verify that your time and time zone are accurate.
Accurate system time may be critically important when establishing connections online.
Let's also head into Settings > General and scroll to the bottom. Do you see a section labeled "Profiles"? If so, there may be a device management profile installed. Typically these are configured by your work or school environment, in which case you'll want to reach out to your IT administrator for assistance.
If you're using any kind of protective case on your device, we also recommend removing it for further testing.
If you find that the same issues persist after each of these steps, reach out to Apple Support via our website here for further assistance:

Take care!
