apache web server 502 error proxy error when direct to an image url

Question

Good day,

I have an Apache web server, and I configure ProxyPass it to my application server.

Everything is work unless the connection to the image in application server. I will hit 502 for the request to image url.

The following is my configuration in httpd.conf:

ProxyPass "/myapp" "https://10.8.1.200/myapp"
ProxyPassReverse "/myapp" "https://10.8.1.200/myapp"
ProxyPass "/api" "https://10.8.1.200/api"
ProxyPassReverse "/api" "https://10.8.1.200/api"
ProxyPass "/image.web" "http://10.8.1.200/image.web" retry=1 acquire=3000 timeout=600 Keepalive=On
ProxyPassReverse "/image.web" "http://10.8.1.200/image.web" 

The /myapp and /api will work perfectly, except the /resource.web.

As the full access of the url for 10.8.1.200 is accessible in 10.8.1.200 itself as follow: http://10.8.1.200/image.web/my.campaign.banner/promo.jpg.

my apache version is :

Server version: Apache/2.4.29 (Red Hat)

Anyone know anything I miss out? or configure wrongly?
