Intermittent 503 error in Elasticbeanstalk (Unix domain socket error in ElasticBeanstalk)

We are running a web application written in Java(tomcat8) hosted in AWS ElastcBeanStalk

Some weeks back we started getting 503 error randomly

When we checked the elasticbeanstalk-erorr_logs

[Thu Mar 03 13:22:12.906144 2022] [proxy:error] [pid 14882:tid 139757338711808] (13)Permission denied: AH02454: HTTP: attempt to connect to Unix domain socket /var/run/httpd/ (localhost) failed
[Thu Mar 03 13:22:12.906202 2022] [proxy_http:error] [pid 14882:tid 139757338711808] [client 172.31.17.0:61382] AH01114: HTTP: failed to make connection to backend: httpd-UDS, referer:
The error logs are suggesting connection error with backend unix socket

When we checked in /var/run/httpd/ folder, there were no unix sockets(.sock files)

But in apache httpd config

<VirtualHost *:80> <Proxy *> Require all granted </Proxy> ProxyPass / retry=0 ProxyPassReverse / ProxyPreserveHost on ErrorLog /var/log/httpd/elasticbeanstalk-error_log
</VirtualHost>

the proxy backend is ip address not unix socket

As per the config httpd should connect to backend ip address(localhost:8080) but why is it complaining about unix socket

Have anyone faced similar issues?
