I use a python flask server in the backend . It run a script which prepare then download an xml file.

this is working fine is script but if script lasts longer than 80 sec it's stopped and http error 502 is displayed and the xml file is not closed correctly and i get this message :

This page contains the following errors: error on line 2373 at column 426: Extra content at the end of the document Below is a rendering of the page up to the first error.

the log file report :

2022-10-11 21:42:54	Error	1xx.xxx.xxx.xx	502	GET /email/xxxxxxxxxx.com HTTP/1.1			1.68 K	Apache SSL/TLS access

2022-10-11 21:43:25	Error	1xx.xxx.xxx.xx		AH00898: Error reading from remote server returned by /email/xxxxxxxxxxx.com				Apache error

I have try the script directly in the server with ssh terminal and it's executed without any error .

the Apache & nginx Settings

the conf setting:
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPreserveHost On
<Location "/email">
ProxyPass "http://127.0.0.1:5000/email"
ProxyPassReverse "http://127.0.0.1:5000/email"
</Location>

I have try some setting as : retry=1 connectiontimeout=180 timeout=180 keepalive=on
without result.

Any suggestion ? Thanks
