Adding HP Aruba AP15 failed as the VLAN
Had already deployed one AP15.
Went to +AP15.
However, could not add it on Aruba Instant On even ping in normal.
Finally, get that related to the Switch - TP-Link TL-SG1226PE (https://www.tp-link.com.cn/product_566.html).
One project vendor sponsored it to us.
Because of its limitation on VLAN mode:
Only 23, 24, 25, 26 can be relative communication.
All others can only be standalone.
All others can only be standalone.
The site could not +AP15 as the VLAN; connection failed.
Changed the Switch to Normal mode.
Worked, then.

You shouldn't have to enter the serial number of your device as part of adding to your site.
If you are adding the AP to an existing site, in the portal then select "Add new devices" under the site settings menu at the top right. When you select it, you can search for your devices and it should be shown to you, if connected on the same subnet as the 2 other APs you have.
Were you following those steps?
If so, you should contact support and they should be able to help you when you provide your AP serial number.
