Hey, I have a really strange problem with matomo.
When I track users, every user "has" the ip address of the host which the virtual machine with matomo is running on. I really have no idea what could cause this kind of problem.
I am very confused and appreciate every kind of help.
This sounds as if you are running Matomo behind a reverse proxy.
See here for how to configure Matomo in that case:
I found the issue. Absolutely my bad. I added a new network interface on my host which messed up my iptables and masqueraded all ip addresses.
