Thx for yr reply, Victor.
I think both the switch & the specific port are functioning. I plugged in a laptop as suggested. It got an IP from VLAN1 if I configured the port on VLAN1, got IP from VLAN2 if configured as VLAN2. Internet connection works perfectly.

The AP ssid is on VLAN1, if switch port on VLAN1 it does not work, but if on VLAN2, it works!!

Then if both AP & port on VLAN2, it does not work either.

Really can't explain!!

Can we get the switch config for that port?

port 28

Great! The VLAN 2 assigned to interface 28 is not tagged. Thus it really doesn't matter what VLAN that is. There are no tags. At this point, the AP will probably work set on VLAN 1, if that's set as untagged on it. When you switch the AP to VLAN 2, it thinks it has to tag the traffic with VLAN 2... tags, or vlan-id. But the switch is only accepted untagged traffic, therefore the packets from the AP are dropped.
