My Agent got an 500 Eroor. How can i fix this? [closed]

hi, 

i tried to set up OCS and solved some problems, but i dont get it finaly working. 

Now the problem is, that the Agent cannot connect to the Server. I get an error from the Agent:

2020][error] Cannot establish communication : 500 Internal Server Error

My ocs Server Veriosn is 2.4 (from the repository for CentOs7)

Agent Version is:

ocsinventory-agent --version

Ocsinventory unified agent for UNIX, Linux and MacOSX (2.6.1)

[root@myserver ~]# 

Erlier i tried the latest version from the GitHub Repo, but don't get it working. 

the ocsimport-reports configuration looks like the following. I made an new VHost for ocd, because  when i leave the standard configuration like mydomain.de/ocsiventory i get an 400 (bad request) error.

All my Domains have there own vhost. So that seeems to be the best Solution for me. 

I tried to find a solution for the error, but found nothing.

- From the apache access.log (debug level):

xxx.xxx.xxx.xxx - - [21/Sep/2020:07:48:55 +0200] "POST /ocsinventory HTTP/1.1" 200 234 "-" "OCS-NG_unified_unix_agent_v2.6.1"

- I enabled the mysql Query Logs. When i run ocsreports-agent i see many SELECT Querys there. DB Connection seems to work. 

- I also checked the Mysql-Credentials in the config files in /etc/httpd/conf.d/

- the Server Version 2.4 semms to be unable to write logs. Permissions for the Log-Dir are set to 777. so i am unable to see if something on the Server Side wents wrong. See also: https://github.com/OCSInventory-NG/OCSInventory-Server/issues/100

The error.log from apache sais nothing to this error. 

I tried to connect from an Agent on the same machine and from a different machine and got the same error

The config is:

 cat /etc/ocsinventory/ocsinventory-agent.cfg 

# OCS Inventory "Unix Unified Agent" Configuration File

#

# options used by cron job overides this (see /etc/sysconfig/ocsinventory-agent)

#

# Server URL, unconmment if needed

server = ocs.mydomain.de:80

#local = /var/lib/ocsinventory-agent

# Administrative TAG (optional, must be filed before first inventory)

# tag = your_tag

# How to log, can be File,Stderr,Syslog

logger = Stderr

logfile = /var/log/ocsinventory-agent/ocsinventory-agent.log

ocsinventory-agent --server ocs.mydomain.de and ocsinventory-agent --server http://ocs.mydomain.de are also not working

When i trie ocsinventory-agent --server ocs.mydomain.de/ocsreports/ i get an 404 error, but 

 curl -IL ocs.mydomain.de/ocsreports/

HTTP/1.1 200 OK

500er FIXED!

After reinstalling the remi-repo i was able to update to Server 2.7. Now the Agents can connect.
But the Problem with the Server logs still exists.
Any Idea?
