Environment

Release : 10.1

Component : API GATEWAY

Cause

only specific interface was chosen under the manage listen ports ( Tasks > Manage Listen Ports > 8443 Properties )

Resolution

make sure port 8443 has set under Manage listen ports properties > interfaces > ALL IPs in cluster 
So any gateway in cluster can use port 8443 

we can check this via sql query 
mysql> select * from cluster_properties where propkey = 'interfaceTags'\G
