I am trying to connect my EAP to IronWifi External Radius Server for user registration and authentication.
Trying to use their customized external web portal but receive an Invalid Request Parameters error when trying to save the external address.

If I remove the part that actually specifies my portal specifically it will save but that just takes you to the IronWifi website, not my splash page.

Is your EAP225 managed by Omada Controller? What's the version of your Controller?

Could you please elaborate on the issue with some screenshots?

The EAP (v3.0 - 5.0.3) is managed by Omada Controller (OC200 1.0) version 4.3.5

My issue arises when I try to link to the external web portal, if I remove everything after the .com it saves and redirects as expected, but that just takes you to their main website and not my specific splash page, the info after .com is my ironwifi unique ID.

Thank you for the detailed information. I've reported this issue to the R&D team for checking.

Thank you for the update, I have actually managed to solve this issue (with the help from the guys at ironwifi), seems that the external portal address needed to end in .com .co.uk, so they helped it reroute and forward to where I needed to go.

The problem seems to be that the external portal address doesn't allow subpath with "/". The R&D team will check the problem and fix it.

Funnily enough with that part resolved I am now having a similar issue in getting my login to authenticate and authorize with the controller url, and its actually throwing up the same error.

To better understand the problem, could you please upload the screenshot for checking?
