The Arena portal of the Montpellier academy relies on the centralized authentication system of the national education. Each staff member (teacher, administrative, agent) accesses it with their academic ID and a password that, by default, corresponds to the Numen until it has been changed. The blocks we observe in assistance rarely stem from a server failure: they almost always relate to an authentication issue or poorly configured application rights.
Strong authentication on Arena Montpellier: what really blocks
Access to certain sensitive applications via Arena (i-Prof, professional webmail) now requires two-factor authentication. A temporary code, generated by an application like Google Authenticator, is added to the classic ID/password pair.

Forgetting or losing this second factor completely blocks the connection. Unlike a simple password that can be reset online, recovering the second factor must go through academic assistance. We recommend saving the backup codes provided during activation in a password manager or on a physical medium kept away from the workstation.
Another common trap: the time zone of the device. Temporary codes rely on an algorithm synchronized to the second. A smartphone with a clock that is off, even by two minutes, generates codes rejected by the server. Just check that the automatic time synchronization is enabled on the device.

To connect to the Arena Montpellier portal smoothly, you must validate three elements before any attempt: correct academic ID, up-to-date password, and functional second factor if the target application requires it.
Service delegation and Arena application rights
The absence of an application in the Arena portal does not mean a failure. Arena is a personalized portal: each agent only sees the applications corresponding to their profile and missions. A middle school teacher, for example, will not see EPSnet, which is reserved for organizing certification tests.
When a staff member needs access to an application missing from their portal, the head of the establishment must perform a service delegation beforehand. This operation is carried out from the authorization management module in Arena. Without this delegation, no user-side manipulation will resolve the issue.
- Check with the head of the establishment that the delegation has been properly recorded in the Arena authorization module
- Wait for the propagation of rights, which can take several hours after validation
- Log out and then log back into the portal to force a refresh of the application profile
We regularly find that staff contact technical support when the block is simply due to a lack of delegation. Identifying this scenario in advance saves considerable time.
Resolving an Arena connection issue related to the browser or network
Connection errors to the Arena Montpellier portal often stem from the local technical environment. The academic server is functioning, but the browser or network prevents access.
Cache, cookies, and expired sessions
An Arena session that does not close properly leaves an expired authentication cookie. During the next attempt, the server refuses the connection with a generic error. Clearing the browser’s cache and cookies resolves the majority of these blocks.
On both Firefox and Chrome, a keyboard shortcut (Ctrl+Shift+Delete) directly opens the panel for deleting browsing data. Targeting cookies and cache is sufficient, without touching the history or saved passwords.
VPN and network filtering
Using a VPN frequently disrupts access to Arena. The official page of the ministry explicitly states that a VPN-type device can be the cause of access disruption. Disabling the VPN before attempting to connect is the first reflex to adopt.
In a school setting, the network proxy may also block certain requests to arena.ac-montpellier.fr. In this case, only the local network administrator can intervene.
ASAP² portal: contact the academic assistance Occitanie
When the problem persists after checking authentication, rights, and the technical environment, the assistance request goes through the ASAP² portal, accessible directly or from Arena itself (section “Resources and Tools”, category “Assistance and IT”).
- The ASAP² portal is available at all times and allows you to submit a request, track its progress, and communicate with the support teams
- Preparing the establishment’s RNE number, the academic ID, and a precise description of the error message speeds up processing
- Phone assistance remains available for urgent cases, but submission via ASAP² is preferred to keep a written record
The Montpellier academy also updates information spaces (intranet, dedicated pages) to report the actual status of the network and applications. Before submitting a ticket, checking these pages allows you to know if the incident has already been identified and is being addressed.
An Arena block lasting more than a few hours after eliminating local causes (password, second factor, cache, VPN, delegation) almost always relates to an incident on the academic server side. In this case, reporting via ASAP² remains the only effective lever for action to obtain a resolution.
