Hello !
Sorry for the subject of my email.
Sometimes, I have some understanding concern in English.
So you want all the configuration of HAProxy ? You can look at the
attachment (haproxy.cfg). I have just used the basic configuration of
HAProxy.
And I have forgotten to mention the version of HAProxy (maybe there are
some differences) : HA-Proxy version 1.8.19-1+deb10u2 2020/04/01.
Also, sorry for the asterisks they seems to be added after my sending. :/
You can see the logs after a restart and some exchange of data.
I have seen that when I change the configuration of my IoT device to a
sending interval of 30 seconds instead of 15 minutes or 30 minutes,
HAProxy works and exchanges between my device and my java server seems
to be made normally. So maybe, it's a problem of timeout.
Also, you can see in the log file, these two last lines :
Aug 11 11:24:30 AS-Freedom haproxy[5371]: 185.99.26.70:60749
[11/Aug/2020:11:22:12.639] srv_java all_java_srv/srv_1 1/0/138128 17
cD 1/1/0/0/0 0/0
Aug 11 11:27:36 AS-Freedom haproxy[5371]: 185.99.26.66:49655
[11/Aug/2020:11:26:45.595] srv_java all_java_srv/srv_1 1/0/50755 5
cD 1/1/0/0/0 0/0
I think they should be appearing when the connection is interrupted
between the server and the device is interrupted.
I will search again about timeouts in HAProxy.
Thanks a lot for your help !
And sorry for the lack of information.
Sincerely.

Can I ask my question here ? Or do I have to write it in an other place ?
This is the appropriate place. However I must admit that your email
looked like spam based off the Subject at a first glance.
In order to test load-balancing, in the config file of HAProxy, I wrote
theses two things :
*frontend* java_srv
*bind* 192.168.0.19:26001
*mode* tcp
*default_backend* all_java_srv
*backend* all_java_srv
*balance* roundrobin
*mode* tcp
*server* srv_1 192.168.0.19:26001
Can you please give your *literal* configuration instead of just the
options you consider important? And please give the configuration in the
original format without the asterisks in there.
Some fast exchanges seems to be made between the IoT device and my
server, but when it have to wait, the connection is cut and the device
is disconnected.
Any error messages? Did you enable logging in HAProxy (you should)? Can
you provide a log message?
Best regards
Tim Düsterhus
