Unable to connect to wired network with 802.1x security and (PEAP authentication)

I am trying to connect to my college LAN and have done everything I was asked to do, but am unable to connect.

The setup:

authentication: PEAP

inner authentication: MSCHAPv2

(and credentials)

Here's what I have tried as of now

  1. I have tried using the GUI but the error wasn't very insightful
  2. I tried connecting using nmcli

nmcli con up iiithauthcert --ask where iiithauthcert is the name I have given to the profile.

I ran the command on a terminal window and ran journalctl -f -t NetworkManager on another

The logs are as follows

Please note that I am sure my credentials are being input correctly because I am dual booting with windows 10 and am able to successfully able to connect to the LAN there (with those credentials)

Please let me know if there is some other information I should provide for better insight into my issue.

The Ubuntu system I am running is 21.10

Any help or advice is appreciated.

Did you even read the log? Look for "`failed`", and find out why the listed script exited with an error status of 2.

@waltinator I did read the error log and the script happened to be a NetworkManager script. I have looked up about that specific error line but to no avail. Could you suggest a way I could get more information on why that script fails?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
