net::ERR_INVALID_CHUNKED_ENCODING 200 (OK)

Good afternoon all,

I'm currently creating a brand new apache reverse proxy on apache 2.4.39 (the former one runs 2.2).
My config syntax is fine (double checked with -t), the proxy job is done by apache, the daemon is up and running, however I get "blank pages" displayed for some vhosts.

Troubleshooting actions :
Try to curl http(s)://theRemoteURL --> worked fine, so it's not due to ACLs
Checked apache's logs --> nothing related

When I display the web browser developper tools, I get this message :
net::ERR_INVALID_CHUNKED_ENCODING 200 (OK)

My server is running Solaris 11.4, and I have multiple vhosts configured.
Here's one of them :

<VirtualHost *:80>
    ProxyRequests off
    ProxyPreserveHost on
    ServerName MYSITE.TEST.COM
    Redirect permanent / https://MYSITE.TEST.COM/
</VirtualHost>

<VirtualHost *:443>
    ServerName MYSITE.TEST.COM
    ProxyPreserveHost on
    SSLEngine On
    SSLProtocol ALL -SSLv2 -SSLv3
    SSLCipherSuite ECDHE-RSA-AES256-SHA384:AES256-SHA256:!RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM;
    SSLHonorCipherOrder on
    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
    <Proxy *>
        AddDefaultCharset Off
        Require all granted
    </Proxy>
    <Location /phpmyadmin>
        AddDefaultCharset Off
        Require ip 1.2.3.4
        Require ip 2.3.4.5
        Require ip 3.4.5.6
    </Location>
    ProxyPass /PJ !
    ProxyPass / http://THEWEBSERVER/
   
    ErrorLog "/etc/opt/csw/apache2/logs/error_MYSITE.TEST.COM_443.log"
    TransferLog "/etc/opt/csw/apache2/logs/access_MYSITE.TEST.COM.log"
    CustomLog "|/usr/bin/logger -t apache -i -p local6.notice" combined
</VirtualHost>

Code (markup):

Any idea ?

 

This could be due to returning the response from proxy service to the browser that response contained the header Transfer-Encoding: chunked try to remove that header before sending the response back to the browser.

 

Thanks for the answer.

How to remove this header, as I didn't specify anything about it ?
