Unable to register APs in Sophos Central, even known good devices, remove/add - same account

Hi Matthew,

Thank you for reaching out to Sophos Community.

Have you tried to follow the following KB for troubleshooting access point 

• Sophos Firewall: Troubleshoot Sophos Access Points
• Sophos Wireless: APX and legacy AP access points fail to register with Sophos Central

Also, "As a test, I have deleted a device from Sophos Wireless - then tried to re-register it." 

Kindly check the FW rule and if the access point has a DHCP lease and can reach outside the network

Thanks for the quick reply Erick. I have an overide policy for the two APX devices to allow all traffic externally. I've also confirmed that the Wireless Protection service is disabled on the XG, and I can see traffic from both devices attempting to contact https://wifi.cloud.sophos.com + DNS and NTP entries.

I'm not able to register the APXs, including one I removed, and trying to re-register as a test.

Hi Matthew,

To verify, Are the AP's configured on the Sophos Firewall before trying to set it up on Central?

nevertheless, can you try to follow the following link and update us? Thanks

AP cannot connect to Sophos Central Wireless

Thanks, I have added, then removed the APXs from Sophos XG management as per that article. I'm afraid they are still timing out attempting registration to Sophos Wireless.

One of the APs was previously registered with Sophos Wireless earlier today. I deleted it, then attempted to re-register it to test if there is an issue with re-registering devices with Sophos Wireless.

Grateful if perhaps you could test this at Sophos too?

1) Delete a known-good APX from Sophos Wireless

2) Factory reset the APX

3) Register the APX back into Sophos Wireless

Hi Matthew,

To verify, 

• When you follow steps 1-2. Did the access point get registered?

1. connect the access point to Sophos Firewall
The access point must be reconnected to a Sophos UTM/XG firewall. 

2. Set up access point
Add the access point under the firewall as a new device as if you really want to use it. If necessary, the firmware on the AP is reinstalled and then the configuration is loaded. It could therefore take a little longer. After about 1-5 minutes, the AP should be displayed as ‘Active‘.

3. Delete access point from firewall
Remove the configuration of the access point on the firewall and wait until it is listed under ‘Pending Access Point‘ again. (Do not disconnect the physical connection).

4. Delete access point from pending
As soon as the AP is listed under the “Pending Access Point” again, it must also be manually deleted here. After that, you can disconnect the cable from the AP.

5. Add an access point to Sophos Central

• I would recommend creating a Case ID on Sophos Support to further analyze the issue as the following KB's have been followed.
  • Sophos Firewall: Troubleshoot Sophos Access Points
  • Sophos Wireless: APX and legacy AP access points fail to register with Sophos Central
  • AP cannot connect to Sophos Central Wireless
• Kindly Share Case ID, for us to be able to follow.

Will try to recreate your case concerning deleting the APX on Central and re-registering.

Thanks again for your help so far.

I can confirm I have tried the steps above and still unable to register the APX devices.

...looking forward to hearing how you get on with the test scenario.

I tried with different ISP, same problem. I'm starting to think it's a problem on the side of the sophos portal.

Erick Jan  - many thanks for your assistance so far. I think there are multiple people now, not just myself experiencing an issue registering APX devices with Sophos Wireless.

Grateful if you could provide us with an update of any testing you have performed?
