Connection error

Hello everyone...

Today something very particular happens to me ... I want to know if someone has happened to me before ... a few hours ago I began to fail, there was no connection and I stopped working ... it was slow, heavy and the service was disconnected, after about 2 hours, when I restart the service for the second time, everything worked perfect until now and has not failed again ...

The traccar log did not tell me anything abnormal, but the apache log if ... I am what I got as common:

[proxy_http: error] [pid 692: tid 139960728401664] [client 162.17.130.215:60788] AH01114: HTTP: failed to make connection to backend: localhost, referer:

[proxy: error] [pid 692: tid 139960665462528] AH00940: HTTP: disabled connection for (localhost)

If you can appreciate everything was error related to Proxy or Http Proxy ... it is a server in Ubuntu ...

The amazing thing is that I stop failing and now it works well ... but what causes this failure? Has anyone had this experience?

Thank you

Looks like server was unavailable. You need to check server logs, not Apache.
