I’m using the PHP tracker for some reason since a while now and I never had any problems.
Since some days, I’m running latest version of Piwik on a Ubuntu server 15.10 and I have a problem:
All of my visitor have the public IP of the server.
The database is on another server.
I tried some solutions as
proxy_client_headers[] = HTTP_X_FORWARDED_FOR
proxy_host_headers[] = HTTP_X_FORWARDED_HOST
and I would like to know if you have more solutions !
AFAIK the PHP tracker is using cip parameter to forward the IP address. Please confirm that the token_auth is still valid. It’s required in order to force IP. It may have been changed after password change for given user.
You can remove these. I assume that you don’t have proxy/load balancer there.
