There are a few vlan configured for the switch:
VLAN Networks Default VLAN (1*), CORP11 - SW (11), OT12 - SW (12), CREW21 - SW (21), Charter26 - SW (26), FreeQuota - SW (33)
The external access is set to Auto.
We can see the Switch is online on IC2 and controlling it via IC2 is fine.
When trying to remote web admin, it is always failing.
I found is that the external access is on a vlan with captive portal.
When I removed the captive portal, I will be able to remote web admin again.
I could set it to custom and force the vlan but the auto function should fine a workable vlan to use in the 1st place.
Is this a bug ?
