Authentication issue unsupported protocol

mary-sc
Hi,

I am trying to connect my esp32 device to an enterprise network which uses freeradius version 3.0.20 and i am encountering unsupported protocol issue as in the log below. However, my phone can connect to the same network. Also, my colleague (unfortunate we are working apart as we are working remotely) was able to connect the same device but he is using the version 2.2.8. What could possibly be the cause of the issue and how to resolve it?

==========================================================================

Thank you so much!

You have posted on Nabble Support. I'm guessing you were intending to post on the forum at:

However, that is a read-only archive of posts on their mail list. It looks as if this is where you need to go:
