My head is broken. Have a site with nodejs at backend behind apache. Some times from react app I see in chrome dev console connections to backend in stalled state or in pending state. after ten or more seconds this connection return 502 error.
apache proxypass config is
ProxyPass /node2023/ http://192.168.0.9:4005/ #retry=1 acquire=3000 timeout=600 Keepalive=On proxyPassReverse /node2023/ http://192.168.0.9:4005/
now config is
ProxyPass /node2023/ http://192.168.0.9:4005/ proxyPassReverse /node2023/ http://192.168.0.9:4005/
Waiting for errors )
Do not understand why i have pending or stalled state of query to server.
I try to restart apache - no effect If i restart nodejs app - one hour work fine.
