First my system description:
I have running server 2019 with php 7.4.15 and running only https, also for Matomo.
Actually there are a Hyper-V with two VM Servers. The fist one is mainly for exchange and the second one runs the web server IIS with Sophos (firewall) , php, Typo3, MySQL, …
The tracking works fine for all internal traffic, but external visits are not tracked at all. So, it should be no problem with the database in my opinion.
I can access to the Matomo page from external without any problem.
Which steps/tests should I do next to figure out the problem?
Thanks for our help, HGA
