Hi Team,
Consider we are using a reverse proxy yyy.com to the domain name xxx.com and while we do reverse proxy xxx.com change their A record from 1.1.1.1 to 2.2.2.2 then the reverse proxy yyy.com stopped working by showing status code as 504 or 499
In order to fix the issue, we have to restart the Nginx of yyy.com the reverse proxy domain. This needs to be fixed.
