Hey Paul,


Thanks for taking a look at this.


With out situation, we re-issued the root CA key (eduroam was updated almost right after).


We were using the latest (at the time, almost a week or 2 now so perhaps there was a more recent update) and also tested removing the app and re-installing the app.


Here is what we did on one phone to try and get it working (it did not work):


  1. Forget the eduroam SSID
  2. Download the geteduroam app (using a different SSID)
  3. Find our profile and install (enter username and password, etc)


We did vary this on a few devices (not forgetting the SSID, etc), but the process was fairly straightforward, however in all cases we could not get them connected.

You don't often get email from paul.dekkers AT Learn why this is important

We tested the migration of CAs and simulaneous use of different CAs, and that worked well on iOS (among others), so it's not an issue I recognize.

I'll see what I can find/reproduce. Can you confirm you're on the latest geteduroam iOS update? (Does it work if you deinstall the App and reinstall?)

We recently changed the root certificate used to sign our EAP server certificate and we are having an issue with iPhone devices and the geteduroam app.


What I know so far


  1. Android works no problem, both on a clean device and a previously configured device
  2. iOS works on a clean device
  3. iOS does not work on a previously configured device
  4. The “” profile manually installed on an iOS device works without any problem
  5. Manually connecting works without any problem


The profile itself looks good.  The static and live tests pass in the eduroam admin, but on a previously configured iOS device we always get a “Cannot connect to network” message.


We use Cisco ISE as our NAC and it reports a TLS error during the negotiating with the client device.


Anyone else experience this?
